Have a read of what the major political parties and groups think about these issues, and make sure you have your say on election day. Watch this space.
Elizabeth Soal Chief Executive, IrrigationNZ
Water infrastructure issues don’t get solved once, they must be addressed as a continuous process in light of changed circumstances.
Irrigation is absolutely critical for New Zealand to be able to grow and produce high quality food and fibre for ourselves, and for discerning overseas markets.
They say a week is a long time in politics, but how about two or three?
As I write this column, the election is still a few weeks away, but it will be right around the corner when you’re reading this. Given the pace of political upheaval and the constant stream of outrage in our newsfeeds, it’s hard to know how much will have changed in just that short space of time. However, the importance of water policy and in getting it correct for this and future generations remains constant. Across the political spectrum, the importance of planning the use and management of this precious resource is agreed. The detail on how that is best done, less IrrigationNZso.has been consistent in our messaging with the government and those in opposition – as a country we need more storage, we need an overarching water strategy to guide decision-making, we need a resolution to Māori rights and interests, and we need a robust and effective allocation framework for freshwater. These are the core tenets of our 2020 Election Manifesto. We feel that without addressing these key areas, we will not realise the potential that irrigation brings to our horticultural and agricultural sectors, we will not be supporting our regional economies and the Māori economy, and we will not be providing resilience for our communities under climate change scenarios. As communities face record-breaking droughts, followed in short order by recordbreaking floods, it is clear that we must act now.

TELLING THE STORY
IRRIGATIONNZ IN WELLINGTON COVID-19 has yet again put a stop to some of our travel plans. However, IrrigationNZ Chairwoman Keri Johnston still managed to get to Wellington for the Food and Fibre leaders Forum to meet Prime Minister Jacinda Ardern, Finance Minister Shane Jones, Minister for the Environment David Parker and Ministry for Environment (MFE) officials, regarding freshwater reforms and water management. She also met with the National Party spokesperson for the environment Scott Simpson, on similar matters. IrrigationNZ CEO Elizabeth Soal met with MFE officials to share her experience with Farm Environment Plans and also to share the ‘Know Your Catchment’ water quality data project. She also shared the project with the Greater Wellington Regional Council. Elizabeth also had virtual meetings with Undersecretary for Regional Economic Development Fletcher Tabuteau regarding water management; Minister for the Environment, David Parker; and ACT spokesperson for infrastructure, Simon Court.

SPRING IS HERE – TIME TO CHECK YOUR IRRIGATION SYSTEM!
The 2019 National Disaster Resilience Strategy identified the risk of natural and cyclical climate variation is increased by climate change, which produces more severe storms andNewdroughts.Zealand is not able to influence when events happen, but we should prepare for climate variability, which means increased resilience and capacity to maintain economic production and supply potable water, during extended periods of dry weather.
ACT believes a partnership approach is best suited to these developments, between central and local government, the private sector, and the communities which benefit from improved resilience and economic activity.
DAVID BENNETT Agriculture Spokesperson, National Party Access to water is becoming a big issue. The recent demands from Auckland City for more water supply shows how this is quickly developing into a major infrastructure issue for New Zealand. Water storage is also an environmental issue as any water infrastructure needs to meet environmental outcomes. National believes that water will be one of the key strategic resources for New Zealand in theRecently,next century.anumber of plans for growth for the primary sector have been released. First, the Fit For a Better World report projected a $44 billion doubling of primary exports, a large portion of which is accounted for by Horticulture. Even Horticulture’s Covid Recovery Strategy places a strong emphasis on the need for water storage. To achieve New Zealand’s economic potential, we need to ensure there is appropriate water infrastructure. Especially in a post-Covid world where our primary sector is our major exporter. Water storage doesn’t come cheap. It requires partnering with the private sector and government, both local and central. Many projects fail from a lack of capital and often the scale is not achieved due to financial constraints. Water infrastructure projects are notoriously difficult to get off the ground but if they can be made to work they provide enormous value.Havingreliable access to water allows land use to be converted to higher value crops, reducing nitrates and improving water quality at the same time. There needs to be a commit ment for farmers, with access to water, to farm within existing limits and meet the highest environmental standards.Thecurrentstateofwater use and manage ment in New Zealand requires change to gain security for urban and rural communities across the country. We need to realise that water is our competitive advantage. To achieve this we need Central Government to take an active role. National has the track-record and the team to make these changes and to provide security for future generations.
SIMON COURT Act New Zealand Candidate – Te Atatu
The COVID-19 event closed our borders and severely disrupted trade and travel, which reinforced that a successful primary production sector is vital for our prosperity, jobs, and our foodAtsupply.thesame time, climatic conditions produced severe droughts in the Hawkes Bay, Auckland and Northland, and water shortages affected community drinking water supplies, crops and livestock.
The primary production sector depends on access to safe and secure water at reasonable cost, yet there are major regulatory barriers to developing efficient and sustainable storage and transmission systems, primarily the RMA.
Although originally set to be in September, New Zealand will now go to the polls on 17 October 2020. If you haven’t done so already, mark it in your diary. It is the date you get to vote for the future of New Zealand’s Government. We know water is always high on the political agenda so we asked each of the major parties and other groups to supply us with some information about where they stand on water. Freshwater policy is always front of mind for IrrigationNZ and we will continue to hammer home the importance of well-informed management when it comes to decision-making around it.
7|SPRING 2020 IRRIGATION NZ NEWS VIEW FROM HERE
Election 2020 – freshwater priorities
The reforms that ACT proposes to the RMA would permit transparent trade-offs to compensate for biodiversity lost as a result of major developments, on the basis that any loss is offset with biodiversity enhancements.
High capital costs and long payback periods for large water storage and transmission systems, combined with the risk of failure in the Environment Court, mean that the private sector is unlikely to pursue projects without a public sector partner to underwrite much of the cost and risk.
This means that projects which failed at the consent stage when the discussion was limited to environment or economy, can succeed when an updated process includes a wider consideration of long-term strategic benefits.
We know that, with climate change, we can expect more acute weather events so it’s important we help farmers and growers get their businesses ready for future drought. Irrigation is necessary and this Govern ment has supported the ongoing investigation and development of smaller and focussed irrigation schemes.NewZealandcan’t take water storage for granted. We will need to store water into the future.Myvision is for a resilient primary sector striving for value over volume and this means irrigation schemes must be environmentally and economically viable, with vital regional infrastructure supported by the Government. This will provide a good balance to ensure better outcomes for all New Zealanders.
The current COVID-19 situation has writ large the importance of our primary sector to New Zealand’s economic wellbeing. While other sectors have been devastated, agricultural and horticultural exports have cranked out yet another record year and to a large extent cushioned the economic blow.
TOM KAY
Freshwater Advocate, Forest & Bird Forest & Bird’s vision is for rivers, streams, and wetlands in Aotearoa New Zealand to be clean, healthy, and full of life. But right now, nature is at breaking point. Most lowland rivers are unsafe for swimming. Three-quarters of native freshwater fish species are listed as threatened or at risk of extinction. Droughts and floods are increasingly causing havoc across the country, sometimes one after the other as recently seen in Northland.Howwemanage and use water to sustain people and the planet is a difficult discussion that we have to have, especially as we grapple with the effects of climate change. Every extreme weather event confirms how deeply our economy, our health, and our way of life depends on a healthy environment. Climate change will affect everything we do – we need to take action to protect our environment, and ourTherefuture.are two sides to managing our fresh water to create a better future for people and theFirstly,planet.we need to protect water with strong rules – a robust National Policy Statement on freshwater management with bottom lines for nitrogen and phosphorus pollution to protect human health and the environment. We need to draw a line in the sand to stop further degradation.Secondly,weneed to restore fresh water by committing to regenerative models of agri culture; to efficient irrigation and farm systems with precision technologies; to reinstating wetlands and riparian margins; to transitioning away from water-intensive land uses; and to repairing and upgrading rural and urban stormwater and wastewater treatment systems.
Irrigation has a role to play in increasing our resilience to climate change impacts, but it can only play that role alongside systems that are inherently resilient themselves. We need to use water more efficiently and more carefully to protect the environment we are so dependent on. New Zealand can manage water in a way that enhances, restores, and works with nature to protect people and the planet. We have to do this because we need nature. But first nature needs us.
Water has been a particular focus for this Government – and will continue to be a focus for the Labour party. We are interested in improving freshwater quality, something farmers and urban Kiwis agree is necessary. Doing so will help protect our farmers’ international reputation for sustainably produced food and fibre and safe guard excellent commodity prices.
DAMIEN O’CONNOR Labour Party Minister for Agriculture Agriculture is my heritage and my passion. It is an incredible privilege to serve in a Labourled Government which is backing our primary producers for the long-term. Access to water is vital to New Zealand’s farmers, growers and rural communities, which provide the grunt for our economy.
New Zealand First believe that water storage is the single greatest opportunity to build resilience and diversify our primary sector and our rural communities.
New Zealand has enviable amounts of water and it is just plain common sense to capture at times of surplus and utilise it in times of need. This provides the opportunity to diversify into new higher returning land uses or drought proof existing operations. With the effects of climate change starting to play out in

MARK PATTERSON New Zealand First Agriculture and Primary Industry Spokesperson
We have delivered on our commitment to freshwater reforms which will stop further degradation, show material improvements within five years and restore our waterways to health within a generation. Our country also faces huge infrastructure challenges with regard to drinking water, wastewater and stormwater. This Government has addressed that through our $761 million Three Waters stimulus and reform funding for councils.Aswerebuild the economy following the effects of a global pandemic, we have an opportunity to build back better than before and factor in resilience for our productive primary sector.
The Maori Party were invited to share their thoughts, however did not respond.
Irrigation technology has come a long way in improving water use efficiency and we want to see further innovation.
The challenge for our primary sector is to continue to grow value while acknowledging the ecological limitations of the status quo. With a combination of increasingly precise irrigation systems, enhanced environmental monitoring capability and tighter regulations we now have the capacity to mitigate negative environmental impacts. It is time to have more mature discussions about water storage. In short, if we are smart we can have our cake and eat it too.
The Green Party is proud of the work it has done to improve the health of New Zealand’s rivers, aquifers and lakes. In Government we have strengthened the freshwater rules in the National Policy Statement Freshwater Manage ment for towns and cities as well as rural areas, and secured significant funding to help farmers fence and plant water ways to reduce sediment and nutrient pollution through the $1.3 billion Jobs for Nature package. We also secured an end to government subsidies for large scale irrigation schemes, since such schemes are a recipe for picking winners by giving some farmers an unfair advantage while waterways lose out due to large scale agricultural intensification.
9|SPRING 2020 IRRIGATION NZ NEWS real time this security of production has never been more important.
New Zealand’s natural freshwater resources: • are finite, • are a public resource, • underpin the Kiwi outdoor lifestyle and our ‘clean green brand, and • are being polluted.
The Green Party instead supports sensible solutions that improve water storage while looking after the environment. That includes improving soil health, protecting elite soils, restoring wetlands, and enhancing catchments health with more native plantings.
The Green Party will invest in and retain public ownership of three waters infrastructure, so everyone has access to clean drinking water and we improve the quality or urban stormwater and wastewater discharges. We will also prioritise sustainable solutions for Thewater.Green Party will invest in local infra structure for rainwater storage, and encourage household water conservation in cities and towns. We will require new buildings to include greywater recycling as part of changing to a climate-friendly Building Code. We will support farmers to plan for climate resilient farming, and ensure Farm Environment Plans address on-farm water conservation, irrigation efficiency, and rain water capture and storage.
The reality is that big irrigation schemes have contributed significantly to the water quality crisis the country is now facing.
The climate crisis is likely to mean longer droughts and more intense storm events, as such retaining more water in the soil and reducing runoff matters more than ever. That’s at the heart of our plan.
We know from polling that New Zealanders remain very concerned about water pollution and how careful political parties need to be in addressing this concern. Three quarters – 76 percent – of those surveyed said they were extremely or very concerned about the pollution of lakes and rivers. Only five perent said they were not that concerned.Theonlyissue people were more worried about was the cost of living, with 80 percent saying they were extremely or very concerned. This shows there is a depth of feeling Kiwis have about the loss of what they consider their birthright. All political parties are on notice that in this year’s election, Kiwis will expect to be able to swim, fish and gather food from their rivers, lakes and streams.
New Zealand First are proud that the Provincial Growth Fund has enabled funding of $85 million for various phases of 30 water storage or aquifer recharge projects during this term of government. With a mandate to continue we will prioritise water storage as a key driver of regional economic development. The long term pay back and flow on to the wider community is beyond dispute and an opportunity New Zealand can ill afford to ignore.

Fish & Game Chief Executive
For example, irrigation has allowed intensive dairy farming to establish itself in unsuitable areas like Canterbury. The scale of the problem is shown by the fact that Canterbury is now using two-thirds of all New Zealand’s irrigation take and its water has become increasingly full of nitrates. Fish & Game does support small scale water storage for the dry summer periods. However, both the direct and indirect fresh water environmental effects must be benign. This means it must be at no further harm to the natural environment, which has already suffered too much damage.

The adverse effects of agricultural intensi fication are well understood and are unambiguously evident in the increasing deterioration of water quality and quantity in an increasing number of waterways.
JAMES SHAW Green Party Co‑leader
By Jeremy Fisher. Jeremy is a lawyer and company secretary. He is a key legal advisor on large agribusiness developments and farming businesses across Australia.
In similar vein, Australia’s historical structuring of irrigation governance through local irrigation trusts, co-operatives and companies, common across most State jurisdictions, has generally supported flexibility and efficiency in transfers between irrigators and overcome administrative constraints on farm business decision making evident in State-level control of irrigation allocations. That government water licencing can be a risk to irrigated agriculture has now been recognised judicially in Western Australia, in Ord Irrigation Co-operative Ltd v Department of Water and Environmental Regulation 2020 WASAT 68, in which the State Administrative Tribunal rejected departmental submissions seeking to reduce a group-level water licence and restrict farmers’ flexibility with regard to crop choice and water use in future years. However, the introduction of economic instruments enabling alienation of water rights from local irrigation needs has come under intense scrutiny in Australia. The Australian Competition and Consumer Commission’s Murray-Darling Basin Water Markets Interim Report (30 June 2020) provides salient insights into the consequences of embracing market mechanisms without coherent governance. The Australian experience suggests that in any new legislation dealing with water rights, New Zealand will be well-advised to avoid the extremes of both unqualified administrative control and open marketisation, instead capitalising on local arrangements where possible. THEREReform of the RMA: choosing the future of NZ water trading
The Report suggests that regulatory constraints are a reason for the low uptake of market-based transfers, a conclusion consistent with more than a decade of New Zealand case law and commentary, which has highlighted tension between the RMA’s exclusion of water permits as property and the way water permits are viewed as property in other areas of law. This is observable in Hampton v Canterbury Regional Council [2016] NZSC 50 and Aoraki Water Trust v Meridian Energy Ltd [2005] 2 NZLR 268 (HC). It is noteworthy that protracted litigation and jurisprudence involving the Court of Appeal and the Supreme Court over the life of the RMA has identified, but not resolved, this contradiction.
VIEW FROM
10 | IRRIGATION NZ NEWS SPRING 2020 New Zealand has completed a comprehensive review of the Resource Management Act (RMA), the law which has governed the allocation of water rights for almost two decades.
The RMA’s replacement legislation will need to resolve this tension as demand for water increases. Behind the Report and beyond existing caselaw, some clues to reconciling administrative permits with market trading may be found in the OECD 2017 Review and current issues in Australian water regulation.
The OECD noted the potential for harnessing the collaborative power of New Zealand’s numerous water user groups, by which shared water permits can be issued to water user groups to manage on behalf of members. Assuming the existence of appropriate governance and internal group rules, intra-group trading has the benefit of allowing price signals to operate in a market linked to a water source, while maintaining overall regulatory and planning compliance through accountability at group level.
The Review Report includes recommendat ions with the potential to change markedly the way dealings in irrigation water rights are conducted.Broadly,the Report recommends that the RMA should be repealed and replaced by a ‘Natural and Built Environments Act’, to reduce complexity and improve overall coherence of the legislation. The Report’s guiding theme is to move away from resource management to a focus on environment. For irrigation, the details of likely change are unclear. Water permits do not receive significant attention in the Report, but it is implied that there should there be more scope for water trading, with the Report recommending:•greateruseofeconomic instruments; and • the future legislation should ensure there is a broad mandate for the use of tradeable rights and permits. Citing the OECD Environmental Performance Reviews: New Zealand 2017, the Report notes: • Although section 136 of the RMA enables transferability of water permits, there [has been] limited uptake of these provisions.
“The opportunity to make a difference is there for everybody in the sector. For Water New Zealand, I think some of this is around how we can help our members tell their infrastructure story so that their decisions are well supported by science, economics, and the regulatory environment.”
For Water New Zealand’s new CEO, swapping a career in electricity to the water sector was easy. Gillian Blythe says it was the call of infrastructure and regulatory reform. Now she is looking forward to the challenges of the coming sea of change in Three Waters delivery and the opportunity to make a real difference.
“Ultimately they got too much work so sent an SOS to London to get on the plane and come to New Zealand for seven weeks.”
It was during her seven-week stint that ECNZ offered her a one-year contract.
Clearly, grappling with the various parts to make up the big picture is what drives Ms Blythe.Notsurprisingly, she is excited to be coming into the water sector at a time of transition and regulatory change.
“And then there is COVID-19, and we all need to be thankful for the sterling work of our essential water workers who were out there keeping water and wastewater flowing during lockdown.”“Thesestorieshelp humanise future invest ment needs, and why we need a regulatory regime for water.”
“People respond to signals and if you don’t have information, or the right information, you can’t possibly expect to get efficient and affordable outcomes.”
11|SPRING 2020 IRRIGATION NZ NEWS
Reflecting on this must underpin our thinking, Ms Blythe said. She says Water New Zealand’s vision statement sums it up ‘Ka ora te wai, ka ora te whenua, ka ora ngā tāngata’ –‘If the water is healthy, the land is healthy, the people are healthy’.
This was a time when power generation and delivery was undergoing major reform internationally and Ms Blythe found herself working on projects in places like Belarus and Uzbekistan.“It’squitean eye-opener when you’re sitting in someone’s kitchen in Tashkent and you realise the gas hob has been left on. So, you suggest turning it off – after all, it’s a bit dangerous – and the response is that matches are more expensive than gas.” This, she says, is an illustration of the importance of strong investment signals.
“For instance, everybody in New Zealand knows someone impacted by the earthquakes, whether in Christchurch or Kaikoura. Like wise, most of us know someone affected by the Havelock North water contamination.”
“I see the significant infrastructure invest ment that’s required in the New Zealand water sector and the opportunities for us all to make decisions that would have a positive difference for communities going forward.
“Water infrastructure is a long-term inter generational investment and we need to make decisions that our grandchildren won’t regret.”
As a child growing up in Derbyshire in England, infrastructure has always been part of Gillian Blythe’s consciousness. The daughter of a structural engineer, Ms Blythe went on to study economics at London University and one of her first pieces of research was looking at the environmental impact of large hydro dams.Fromthere, she completed her master’s in environmental economics and started working as an economic consultant in London, thinking about issues around climate change, ozone layers and the like. But that was back in the 1990s and “no one was paying you to do environmental work” so a natural pathway led to consultancy work in the electricity sector.
“We need to think about what climate change is going to mean for those parts of the country that will see an increase in flooding, or those regions with reduced rainfall that will have storage issues. Looking forward we will need to make sure that we have an appropriate balance of demand measures as well as infrastructure investments.”
New CEO for Water New Zealand
“I remember going back to England and being on holiday and thinking about the opportunity and deciding that I didn’t want to get to 60 and wonder if I’d made a mistake.” So she came back to New Zealand where she was part of a team of people looking at creating the market rules for a deregulated market-driven electricity sector. “We helped write the rule book, it was a fascinating project.” Then, on a personal level, came the decision about where to call home. By that stage Ms Blythe had met her future husband, also working in the electricity sector in New Zealand.Andaftersome consideration, the decision was made to live here permanently. Fast for ward to today and Ms Blythe now lives in one of Wellington’s hillside suburbs with her husband and their two teenage boys. Remember the Government reforms of the late 1990s that determined that ECNZ would be split into three separate state-owned enterprises? Shortly after the decision to settle more permanently in New Zealand, Ms Blythe was asked to work in the Electricity Reform Transition Unit.
“With a small group of colleagues, we worked on the split of ECNZ which formed Genesis, Meridian and Mighty River Power which is now known as Mercury.” She said looking back at that era, and despite the controversy around the split up and deregulation, the reforms were successful. “You’ve now got a number of different parties investing in generation, you’ve got strong retail competition. All companies, including the larger players, have to lift their game because you’ve got new entrants coming in with new offerings, new innovations.” Ms Blythe joined Meridian post the ECNZ split, where she established and led the regulatory team through a multitude of reforms. Gillian then took on the role of Head of Strategy at Meridian for six years before finishing at the end of 2019.
It was electricity reforms that led Ms Blythe even further afield from her then-home country – down to New Zealand. “In 1994 the Melbourne branch of the company I worked for, London Economics, had a contract with the New Zealand Govern ment looking at restructuring the electricity sector, and creating a competitive market.

Regional authority planning – new freshwater processes
The new NPSFM requires all regional authorities to implement it “as soon as reasonably practicable.” That means that all regional councils must amend, update, or implement new planning documents (such as Regional Policy Statements and Regional Plans) to implement the new NPSFM and these must be notified by 31 December 2024. However, Councils may determine that their current Policy Statements and Plans already implement the new NPSFM. If there is a “dispute” about this (for instance, a person or group could initiate judicial review proceedings against a council if that person thinks that the NPSFM has not been implemented by the region), the onus is on the council to prove that their instruments do implement the NPSFM, rather than the other party having to prove that the NPSFM hasn’t been implemented.
The new regulations and national environmental standards, such as stock exclusion, may come into force prior to new regional rules and policies being introduced.
New freshwater planning process for regional councils’ policy statements and plans. Freshwater hearings panels replace traditional regional council-appointed hearings panels for freshwater planning instrument hearings. Freshwater hearings panels are not limited in their recommendations to regional councils to only matters raised in submissions By 31 December 2024 to implement new NPSFM.

Local authorities are not required to make changes to wording or terminology within in their planning instruments simply to match the wording of the NPSFM – changes are required where they are substantive to implementing the NPSFM. If they do wish to make minor (non-substantive) changes to wording or terminology, a local authority does not have to go through the standard plan change process to do so.

Breaking a world record – not only once, but twice – is no easy feat, and a Mid Canterbury grower says he could not have achieved it without irrigation.
“Irrigation is crucial to running our business – the seasons change so much year to year.”In2017 they broke the Guinness World Record for the highest wheat yield with 16.791 tonnes per hectare. Now, three years later, they have surpassed this with a crop yielding 17.398 tonnes per hectare. On average irrigated wheat in New Zealand yields about 12 tonnes per hectare.
Eric and Maxine Watson farm at Wakanui just out of Ashburton, a 490-hectare fully arable farm which is 97 percent irrigated.
Eric and Maxine Watson at their farm in Wakanui, Ashburton.
The Kerrin wheat, a feed variey, was sown in April 2019, and harvested on February 17 this year (the record recognition was delayed due to COVID-19).MrandMrs Watson have farmed at ‘Rangitata Holdings’, Wakanui, Ashburton for 27 years, having previously farmed at Ealing, on the north bank of the Rangitata River. Hence, Mr Watson has been growing food for a very long time: he says it is like “having an extra-large vege garden.” Alongside wheat this year they grew a variety of grasses for seed, also chicory, plantain, spinach, radish, pak choi and fabaDecisionsbeans.

about which crops to grow are based around paddock history, national and international markets and financial return. Wheat usually makes up about one-third of the total farm area. Last season a great growing season, with warm days, cool nights, and high sunshine hours, but it was also thanks to their reliable irrigation system, which was an integral part of breaking the record. “We couldn’t grow the wheat to this extent or farm without irrigation, we’d be very restricted in the crops we could grow – overseas buyers don’t like crop failures.”
The farm has a linear irrigation system which is supplied from four wells on the property with VRI (variable rate irrigation) on seven of the nine irrigators for maximum efficiency and accuracy of water application.

Neutron probes are an essential tool, (read weekly, to determine soil moisture levels, the amount of water the crop is using, and how far away the crop is from stress point).
“The record attempt begins before sowing with the area being surveyed, it’s monitored throughout the growing season and on the day the process has to be continuously videoed with every load run over a certified weight bridge. It does cost to enter and it’s really beyond an individual to manage it – we are very grateful for the support we have had from the Bayer team, especially our agronomists and other agricultural consultants throughout it.”
Mrs Watson said compliance was intensifying and has changed drastically in the couple’s time farming, “it’s important we do these things, it’s all part of being a farmer these days.”Thepair love the land, and both love growing things and agree “we get a lot of pleasure out of growing a good crop.” “If you don’t look after your soils, you’re not going to grow a good crop it’s the most important thing for us – the soils are so important and making sure we’re not wasting resources.”Ofhisinvolvement in farming Mr Watson said, “I could never see myself doing anything else.”“Thebestthing (and I’m sure it’s the best thing for most cropping farmers) is sitting in the header at harvest time and knowing all your work has paid off.” When asked if he thought he would try and beat his own record Mr Watson said he would “just have to wait and see.”
Mr Watson said the idea to try and break the record came from his son, Philip, who said he would shout his dad a magnum of champagne if he got it.
“The agronomical knowledge available now is amazing – people put so much work into trials and analysis.”

“We have probes in every paddock: wheat like any plant needs water at the right time and too much or not enough can have a detrimentalFollowingimpact.”the2017 record Mr Watson changed from granular nitrogen application to liquid nitrogen, after observing considerable stripping across the crops. He said this had been a significant factor in increasing their yield.“Theliquid N is applied through the sprayer – it’s very even in distribution, more efficient and you are more flexible as to when you can put it Mron.”Watson said throughout his time farming he had witnessed a big shift in the technology and information available.

Mr Watson said although the field was under cover it could still get really cold, therefore, they also use light and heat lamps to encourage growth.
Looking after the field that sits beneath the roof of the only fully covered natural turf stadium in the world comes with its challenges, but having irrigation helps get it ready for game day.
He said having the field right in preparation for events was a big part of his job. “A lot of the rugby games are televised therefore not only does it need to be performing well it needs to look good.”
During his apprenticeship, he also took on some work at Forsyth Barr Stadium and, before long, landed a role there where he completed his Throughoutqualification.histimeatthe stadium Mr Watson has improved his knowledge to help him take on the manager role two years ago.
Of course, being a covered stadium meant the field never got any rain on it, nor did it get much sunlight – only 50 percent light was received through the roof, therefore irrigation was vital, and if it wasn’t for irrigation Mr Watson said there would be no field to play on. “Irrigation is absolutely crucial to managing the field, we can’t rely on any rain, we also don’t get much light, so the grass can become very weak.”Thefield, which is 9,200m² (just under a hectare) is home to 40 popup sprinklers, which could be operated remotely. In the growing months from October through to March, five to six millimetres of water were put on each day and over the winter months about one to two millimetres are put on across a week. Any dry patches or spots the sprinklers did not reach were hand watered. Approximately 800 kilograms of nitrogen was put on the field a year.
A passion for sports and turf – hand in hand
Forsyth Barr Stadium turf manager, Michael Watson, doing what he does best.
“I’ve just loved every minute of it … sitting in a classroom wasn’t for me and when I discovered this job, getting out of bed each morning was easy”
He soon had a pretty good understanding of what the role entailed and took on a three-and-a-half-year apprenticeship as a groundsman at Balmacewan Golf Club, in Dunedin.
“ We monitor the soil moisture super closely heading into events like these, if it’s too low the field will dry out and if it’s too high it will turn into mud, we don’t want either of those things.”
Mr Watson grew up in Dunedin and at the age of 13 did a day’s work experience for a local golf club as part of his school’s workday.

“With an outside field or turf there is more margin for error with the irrigation, because you can rely on getting a bit of sunlight and rain –however being undercover we can’t, therefore we have to have the irrigation system as close to 100 percent accurate as possible.”
Mr Watson’s primary focus was daily monitoring of the field such as keeping track of what was going on beneath the ground, making sure the moisture levels were right as well as what was happening on top to make sure the grass was performing. Between he and another staff member, they are responsible for the day-to-day maintenance of the field.
“You can have the best-looking grass but it might not be the right soil moisture content for a game and how it is can really affect the play … a sign of success is always when people say it was good to play on.”
The first pile of the stadium was driven in the ground in winter 2009 and was officially opened in 2011 ahead of the Rugby World Cup. Since then more than two million patrons have enjoyed events on the pitch from top international sporting events to concerts, festivals and more.
However over time there had been a shift in focus from not necessarily having the best-looking field.

Irrigation is a crucial element to the only fully covered turf stadium in the world.
The Forsyth Barr Stadium field was regularly home to concertgoers and the set up for concerts often involved a big pack-in and pack-out, therefore an extended period where it was not possible to irrigate. For standing concerts, the field was fully covered. For seated concerts, just the walkways were covered.
“We monitor the soil moisture super closely heading into events like these, if it’s too low the field will dry out and if it’s too high it will turn into mud, we don’t want either of those things.”
Mr Watson said a highlight of his career would have to not only be “the big rugby matches” but also the concerts in 2018.

“We had three concerts over four nights, the place was absolutely buzzing, however, it was a long time for the field to be covered … I can still remember pulling up the floor after being under cover for six days and being pleased with how good the pitch had handled it.”
Mr Watson said turf management had been a great career for him, “I love it, I struggle to see where else I would be.”
“When I was a kid growing up I loved sport from basketball, rugby and golf however I didn’t really have the skill to play it at the top level … however this way I’m involved with top-level sport, just not playing it.”
Unlike many other stadium fields where the turf was grown off site, the Forsyth Barr stadium field was renovated every three years. The previous field was lifted, and new seed sewed to plant a new one. “I consider that a big highlight and cool to be a part of … it can be stressful to have it back operating in time but it’s pretty exciting when you go through the process.”
“It’s a bit contradictory that I say I love my job because you’re outside given the field is under a roof! However, I love it, you’re outside enjoying it and being hands-on.”

“In another five years we have no idea what the patterns are going to be like but it’s good to know we’ve got water.”
“It was a big decision and a big financial investment for us to get irrigation, however I have never regretted the decision, it has allowed us to use our land better and we will continue to be able to in the future.”
Craft beer production in New Zealand is on a high, and it all starts with irrigation. From paddock to malting to brewing, the process to produce outstanding beverages is championed by hard-working, passionate people.
“It’s a great versatile crop and presents different challenges.”
Where it all begins – Hororata farmer Tim Cookson with barley ready for malting.
Mr Cookson said one of the challenges of introducing the barley was integrating it with the rest of the whole system.
“We’re lucky in New Zealand to have abundant water, we might as well use it, it gives us options.”
Mr Cookson said all farmers and growers would say it would be great to be able to stare into a crystal ball and predict the weather patterns and trends for the future, and having irrigation meant, regardless of the climate, he would be able to continue to keep producing.
“Everything needs to line up and work in with the stock, nutrient budgets and more, it’s all part of the challenges we have now.”
“As soon as we had the water, he was on the phone telling me to get the barley in … it was a great decision and is something I really enjoy doing.”MrCookson has now been growing it ever since.“Wewould not be growing it without irrigation, we might get it good once and again but without the irrigation it definitely wouldn’t be sustainable for us.”
Mr Cookson is a friend of Doug Michael at Gladfield Malt, who had always encouraged him to grow malting barley.
The Laureate barley was planted at two separate times in the spring behind paddocks that had been used for winter crop and took approximately 150 days to grow before being harvested in the summer. It was then stored on farm before going to the malting plant. The barley straw was then fed back out on the farm as stock feed.
From paddock to bottle
Growing malting barley was not always on the cards for one Canterbury farmer, however the introduction of irrigation has allowed it to become an integral part of his farming system.TimCookson farms in Hororata and is a fourth generation farmer at his and wife Lucy’s farm ‘Pinewoods’ which was first purchased by his great-grandfather in 1925. He first started getting water for irrigation after development in 2015. Prior to having irrigation, his focus was sheep, dairy grazing and a small amount of cropping, however reliable irrigation unlocked a lot of potential for his land and growing malting barley was one of Thethem.460-hectare property, which is 95 percent irrigated, now grew a range of crops from grass seed, clover seed, hybrid radish, hemp – for the first time last season, and more, as well as ongoing dairy support.

“I didn’t want to be a dairy farmer, it’s a great career, but it wasn’t for me … I had always enjoyed barley and knew we could grow it well and saw the craft beer market as an opportunity.”
Mr Michael always aspired to do something different and started developing the business soon after he left school and when returning home after a shearing stint, bought some of the property himself.
Mr Michael met his wife Gabriella when she was visiting New Zealand from Brazil, and the pair have worked together since.Aftergrowing their own barley for many years Mr and Mrs Michael decided to create their own craft malting plant and when a bare paddock was turned into one in 2004, Gladfield Malt was born. The operation is now a 170-hectare irrigated property which was not only home to the malting plant but also grew barley.“Iwanted to go to the next level and produce a product to sell directly … we’re in some of the world’s best barley growing areas, having a maritime climate, good soils and water for irrigation.”
Mr Michael was primarily focused on the operations of the grain and malting plant while Mrs Michael looked after the salesTheand marketing.craftbeermarket was hard to break into Mr Michael said, as New Zealand brewers previously tended to import their malt. “We slowly developed the market and originally just malted our own barley (which we still do) before we started buying it in, we slowly developed the market day by day, year by year … Gladfield Malt owners, Gabriella and Doug Michael, stand in a paddock of young barley right in front of the processing plant in Dunsandel.
A passion for barley and the desire to do something different was the beginning of Gladfield Malt – which now provides malt across New Zealand and the world.
Doug looks over the controls of the germination process. Although there is a lot of technology involved it still takes a lot of judgement from an expert to make sure the process is done correctly.
Doug and Gabriella Michael are the owners of Gladfield Malt in Dunsandel, Canterbury.
Mr Michael is a fifth-generation farmer at ‘Gladfield’, traditionally a sheep and cropping farm.
From barley to malt
Mr Michael said irrigation was crucial to what they did.
“Our main goal is to provide good malt to our customers and without good barley we couldn’t do that and do it consistently … it’s so important to have irrigation.”
Germination.
“We are so lucky to have passionate farmers who supply us. We’re precision farming in New Zealand now, high quality malting barley is a result of good soils, a unique climate and water, and people to consistently grow a good product.”“Ifwedidn’t have irrigation, we might have a good year every now and again, we wouldn’t have access to the top-quality barley like we do.”MrMichael said like any business the whole thing had been a challenge, but that was the best part.
Doug checks on the grain during the germination process.
Not only did Gladfield Malt get made into beer in New Zealand but it was also exported to Australia, which was their biggest market and Asia, the second biggest market, as well as other destinations. They also provided malt for the baking and distilling industries.
growing our own barley used to be everything however now it’s a small part of our business.”
He said not only were the growing condi tions and soil important but, to have full grain it needed to be watered appropriately.
The malt is then roasted to further create different flavours and ultimately different beers.
Mr Michael said the business had gotten much bigger than they had originally planned. ‘’ There’s no secret to growing a business, the harder you work the luckier you get, having good people around you and staff is so important.”“Alwayshave faith in yourself, ask questions and learn but ultimately you have to make your ownGoingdecisions.”forward Mr Michael said they planned to continue looking ahead and working on producing the best product possible, and both Mr and Mrs Michael enjoyed seeing their children Isabel (13), Fred (11), and Trev (9) learn and experience being part of the “Maybebusiness.whenIretire, I can go back sheep farming.”
THE MALTING PROCESS
Hops is also an integral ingredient in beer. See our previous feature on Tasman hops growers in the Winter 2019 issue of IrrigationNZ News. Visit our website to view this story: www.irrigationnz.co.nz “There’s some sort of challenge every day.” As well as competition, making sure their malt was top standard for a constantly evolving craft beer industry was trying, although only three varieties of barley came through the door, 34 types of malt went out it. “Every brewer is different in what they want. The biggest challenge is making sure we achieve their expectations, having happy customers was a real measure of success, I get a lot of job satisfaction from happy customers and ultimately people enjoying the beer.”
The barley is then cast into germination boxes where it stays for five days. Here growth and modification of the grain occurs. Modification is the breakdown of protein and carbohydrates and results in opening the starch reserves, turning starch into sugar. Moisture levels and temperature are controlled via airflow and water spray.
6. Cleaning and bagging The malt is then cleaned and bagged into one tonne or 25 kilogram bags or sold in bulk.
The last job before the malt goes out the door – bagging.
5. Roasting
4. Kilning The grain is then dried to prevent further germination and flavour is added.
1. Cleaning When the barley first arrives, it is graded and cleaned.
LEARN ABOUT THE PART IRRIGATION PLAYS IN GROWING HOPS
2. Steeping This is where the grain is cleaned and brought to life with water and oxygen. This is done by steeping or immersing the grain in water, followed by a rest period that allows the water to be fully absorbed. The absorbed water promotes the growth of the new enzymes and activates existing ones. This generally takes 24–48 hours.
3. Germination
Malt is a germinated cereal grain that has been dried in a process known as malting. Malt is one of the four essential ingredients in producing craft beer. The process of malting involves three main steps – soaking (known as steeping), next is germinating and finally heating or kilning the grain produces its final colour and flavour.
“The first beer we brewed was of course Yorkshire Bitter, which you generally can’t get in New Zealand,” Mr Limber said. “Our birthdays are both in October and we made two 20 litre kegs of it and took one with us on our birthday holiday and sent another one to a beer festival where it very quickly sold out.”Sincethen we have brewed it constantly as well as plenty of other varieties, we have added over time – they have gone from having a 20-litre home brew kit to an 800-litre commercial kit. The brewery was originally just that. However, two years ago they built a brew bar Dave Dixon (left) and Mark Limber – working during the brewing process.
To the final product
A yarn over a beer and a joke about making the tipple themselves turned into a reality for two mates from Yorkshire, and they are now selling it within metres of where it is made. Mark Limber and Dave Dixon – lovers of beer and music – purchased Two Thumb Brewing Co. in 2017 but their partnership goes back many years. The pair grew up in Doncaster in the UK and at a young age were in a band together “thinking we were going to be rock and roll stars,” Mr Limber said. However, Mr Dixon left the UK in 1992 and the pair did not stay in touch. Eight years ago, Mr Limber made the move to New Zealand. After speaking to a mutual friend, he informed Mr Limber that Mr Dixon had in fact also made the move to New Zealand. On contact they discovered they were both in Christchurch and decided to catch up for a beer, a Two Thumb beer of course. A few beers deep they said if the brewery ever came up for sale, they would purchase it – and a week later it did. They stuck to their word and took over the brewery in September 2017, “it’s fair to say we were terrified when we first started. We knew nothing about brewing, and were terrified contemplating what had we gotten ourselves into,” Mr Limber said. The previous owner stayed on with them for three months to teach them the ropes and then following that it was over to them, who both had, and still do have, other full time jobs.

onto the back of it which now accounts for about 60 percent of their business and is open from Thursday to Sunday.
Step 2: Mashing This is where the malt is mixed with hot water in a large vat to extract the sugars
Step 5: Fermenting The wort is then transferred to the fermenter via a heat exchanger to cool it to 25˚C. The yeast is added. Inside the fermentation tank the yeast eats the sugars and produces alcohol. This takes about a week after which it is transferred into a chilled storage tank for conditioning Step 6: Finishing Touches Stored at four degrees all particles in the beer naturally fall out and the beer clarifies. Two Thumb do not filter their beer, preferring traditional methods. CO² is added at this point to make it fizzy if required. Mark gets the kettle ready for the brewing process.
“Month to month we make different beers – the trends are always changing; it will be interesting to see what the future holds.”
Mr Limber said the pair are small local brewers and being able to use local products to do so is a big part of their values. “We have everything we need to brew beer here in New Zealand and have great access to a variety of malt to do so.”

As well as the bar, Two Thumb also supplies some supermarkets, bars and restaurants as well as showcases their craft beer at festivals and events.
Step 1: Milling Malted barley is crushed in a grain mill. Two Thumb Brewing use a range of malts with a range of flavours and colours depending on what type of beer they are making.
Both Mr Limber and Mr Dixon enjoy brewing together “it’s a lot of hard work but we get on well and enjoy the whole process.”
THE BREWING PROCESS: Brewing beer is the process of extracting sugars and flavours from malted barley adding hops and fermenting, so the liquid creates alcohol.
Step 3: Sparging The grain is rinsed to extract all the sugars and extracted into wort Step 4: Kettle Now the wort is moved to the kettle and boiled. During this the hops are added at different times depending on the flavour requirements.
As the business grows Mr Limber said they would like to be able to do it full time in the future but for now they really just do it for the love of it, “we have learnt so much and the craft beer market is a hard one to crack … trends are always changing.”
“It’s great to have a reliable source of malt as without it we couldn’t make our beer!”

Protecting Maori rock art in South Canterbury South Canterbury has the highest density of Maori rock art or tuhituhi o neherā in New Zealand and, while some locations are public, the vast majority are on private property.
The art is particularly vulnerable because of the materials used to create it – pigments such as soot and kokowai (red ochre) – and the fragile limestone ‘canvas’ to which the art is applied.
Working closely with Ngāi Tahu Rock Art Trust, rūnanga and landowners, Rosemary will dedicate part of her role to advising on the potential impact of irrigation and farming on ancient limestone rock art, called tuhituhi o neherā.
Rosemary’s Poū Matai Kō role centres on raising awareness of how to use the land and environment in way that supports mahinga kai traditional resource gathering and sustainable ecosystems. She has a real interest in freshwater fish such as tuna and īnanga (eels and whitebait) having studied native freshwater fish for much of her career in fisheries conservation.
“There’s a growing appreciation of our native freshwater species and many of these are now ‘at risk’ and some heading towards being ‘critically threatened’ due to changes to their habitat.
Rosemary, who has whakapapa to Ngāi Tūāhuriri Kaiapoi, says it’s a “great privilege” to participate in protecting these taonga along with the manawhenua and kaitiaki of Moeraki, Waihao and Arowhenua.
Mahinga kai targets are now included in Farm Environment Plans and Rosemary is available to help South Canterbury farmers make these targets relevant to their properties.
After many years as a fisheries scientist and DOC ranger in Canterbury and Otago, Rosemary’s aim is now to help farmers protect and enhance native plants, animals –and even precious Māori rock art – on their properties.

Hundreds of drawings in South Canterbury, some of which could be up to 1000 years old, are susceptible to damage or destruction from changes to land use, exposure to the elements and environmental changes. Such sites are a taonga to Ngāi Tahu who are actively involved in their conservation and ongoing management.
The Orari Temuka Opihi Pareora Water Zone Committee supported the inclusion of measures to protect the art in its recommendations to councils on water management as part of its Zone Implementation Programme Addendum (ZIPA). Provisions for rock art protection are also included in Proposed Plan Change 7 of the Land and Water Regional Plan.

Heading into summer, most farmers will have already selected the paddocks for next season’s winter feed but there are still key actions that can minimise environmental risks and to protect the future health of your soils. Land Management Advisor Ian Lyttle shares some useful tips to make sure you are well set up for winter 2021.
Have a good look at the blocks you’ve chosen, with the greatest focus on the steepest areas and the gully or swales that water will flow through before exiting the paddock.
Many farmers are achieving good results using direct drilling, which reduces damage to soil structure and sediment loss. The direction of cultivation is important and contour cultivation across the slope significantly reduces sediment loss risk.
Steep slopes pose greater risk to sediment loss from highly erosive run-off water, so please leave them in pasture to keep your soil in the paddock, where it belongs. In some cases, you may still be able to decide to go grass-to-grass in a steeper paddock and select a flatter paddock for winter feed. Keep in mind too, the future years and how you can get your regrassing done and select lower slope winter feed paddocks for the future.
Stock movement is an important risk factor that farmers can manage. The time stock spend moving on the paddock can be reduced by having well-fed stock, using back fencing, using portable water troughs and planned placement of baleage.
Your winter grazing management plan is all about recognising how to manage the risks to your soil and waterways and preparing management practices to mitigate the risks of soil damage and nutrient loss. It should be prepared well ahead of winter, shared with key operational staff and can be part of your Farm Environment Plan. DairyNZ and Beef + Lamb New Zealand have templates and procedures on their websites that you can use and adapt. Cattle and deer create a greater risk than sheep. This can be mitigated with strategic grazing practices, grazing top down, and protecting the critical source area or swale.
The swales in the paddock provide the last opportunity to keep soil and nutrients in run-off water in your paddock or on your farm. They are your critical source areas. Best practice is to leave the swales in pasture to filter out sediment in the run-off water.
On/off grazing, where the animals are taken off after they have filled their bellies, allows them to get their daily ration of winter feed, and to graze or rest in a more spread out area and to reduce soil damage and sediment losses.Strategically grazed catchment
Take care when establishing your crop
Prepare your winter grazing management plan for the coming season
Soil type is also important, as heavier clay soils are more readily damaged and susceptible to sediment losses. If you’re planning to graze in paddock with heavy soil, you will need to have a plan to move stock in wet weather.
Gearing up for next winter’s grazing
Take stock of your paddocks’ risk areas
Winter crop grazing is recognised as high-risk environmental activity that can contribute more than half of a farm’s annual nutrient losses. It is critical to take action to reduce runoff and sediment loss to help future production on farm and protect our waterways. No one likes to see the worst impacts of winter grazing in a wet year.
Crop establishment is the next critical factor, as certain cultivation methods can greatly increase the risk to soil degradation and loss.
Crops that are more likely to be successful include short rotation ryegrasses, oats, barley and wheat – plants which have larger seeds. They may take a while to germinate, but once they do, they begin taking up those excess nutrients.
Ben Johnson talks to fellow farmers during a winter grazing workshop held at his Timaru property.
• block set-up (early summer/pre-grazing)
The guide, which is available on our website, aims to give FEP auditors the necessary guidance to assess their level of confidence that farmers are meeting environmental targets for winter grazing. These targets include evidence of planning and mitigations to reduce potential nutrient and sediment run-off from paddocks into waterways. They are an important step towards better managing the impact of winter grazing on water quality, soil health and mahinga kai values. “We know that winter is a demanding time for farmers but that is why having a plan for grazing in bad weather is even more important,” says Senior Service Manager Nick Daniels.

New winter grazing guidelines supporting best practice
Ian Lyttle (centre in blue shirt), Land Management Advisor at Environment Canterbury, discusses ideas for grazing this Timaru paddock over winter.
• paddock selection (winter/early spring)
Think about a catch crop for next year Research into catch crops has shown them to be effective in reducing nutrient losses from winter feed crops and to also have a net financial benefit.
Workshops with farm auditors have been held. We encourage auditors or farmers to get in touch with us if you are interested in learning more about auditing for winter grazing.
The job of a catch crop is to grow when soil conditions are too cool for many pasture and crop seeds and to absorb nutrients from the soil and reduce leaching losses below the root zone. These nutrients accumulate in the soil during winter crop grazing, from dung and urine and mineralisation of soil organic matters, such as crop residues. Post-winter is one of the riskiest times of the year for nutrient leaching losses.
We hear concern about how catch crops may disrupt the conventional rotations, but they also provide options for farmers. These include having high-quality leafy forage earlier in the spring, more forage for baleage, or even the option for whole-crop silage or grain.

FISH SCREENS
29|SPRING 2020 IRRIGATION NZ NEWS
Adoption of Good Practise Fish Screening Project. Fish screen design and installation involves significant investment. Given the large capital outlay ahead for irrigators, clear expectations need to be set around how to achieve effective fish screens, alongside the provision of greater certainty that the designers and installers of fish screens can achieve long-term compliance for irrigators.
• Field and laboratory trial scope and design methodologies have been defined.
Next steps include engaging with the manufacturing industry and taking steps for installation of exemplar trial screens; and a review of year one lab trials to assist with the development of the year two lab trials. Further information including reports can be found on the IrrigationNZ website, www.irrigationnz.co.nz/KnowledgeResources/FishScreens
• Identification of three sites suitable to address compliant design. These sites cover ‘typical intake locations’ and represent a range of flows and challenges. They are small to medium in size and exclude large takes. Agreement with landowners of the three sites to participate in the project has been ben achieved and preliminary site assessments undertaken.
In late 2019 IrrigationNZ (on behalf of the New Zealand Fish Screen Working Group*), received a grant from the Sustainable Farming Fund to further research fish screen design criteria. The aim of the research is to provide clear and simple guidance on fish screen requirements and provide solutions and guidance on existing fish screen deficiencies.Thisisatwoyear project and includes identifying knowledge/data gaps, consideration of biological criteria, technical, engineering and design considerations, manufacturing and installation, maintenance and operations, laboratory and field trials, and compliance and planning matters. In addition, industry extension to improve current design and installation capability to meet the impending demands of abstractors who are required to bring their screens up to standard, or for those installing new screen arrangements and need certainty around the effectiveness of their screen, post installation and an education component are included.
Project update from IrrigationNZ
To date the following has been completed:
In year one, the project involved two experiments being run for an irrigation season (September 2019 – May 2020) at two Lincoln University sites using perennial ryegrass/white clover pastures. For the trial, two different treatments were applied to different trial plots. Firstly, plots were created to replicate the current “normal” practice of applying a fixed rate (25kg/ha/month or 200kg/ha/year) of granular nitrogen on a monthly schedule. Then additional trial plots were established using fertigation to apply the same fixed monthly rate as a liquid formulation on a weekly (6.25kg/ha) and monthly (25kg/ha) schedule. The different trial plots were then compared for the following values: the pasture production (yield); pasture composition (species diversity); and feed value. As the first year of the project is considered the “baseline” year, the project team worked to identify any potential significant agronomic differences between the application and timing of two different formulations (granular and liquid) of nitrogen fertiliser at the same monthly rate. Although there were some recorded variations in both pasture yield and composition during the first year of trials, both trial plot experiments normalised by the final harvest in late March. With the results taken into context of a single year’s worth of data, the project can move into the second phase of continuing the initial trial plot experiments to build on the baseline knowledge but also include the addition of a reductions trial. This will be the basis for designing the year two trial which is currently being finalised.
Although it may look like a normal irrigation system, this pivot not only irrigates but also provides fertiliser for pastures through a fertigation system.

IrrigationNZ is grateful to also have the support of Ballance Agri Nutrients, Rainer Irrigation Ltd, Pamu Farms of New Zealand and Molloy Agriculture Ltd for the fertigation project.

• What are the equipment options for fertigation and to which irrigation system types are they best suited?
• What are the environmental benefits from the adoption of fertigation?
30 | IRRIGATION NZ NEWS SPRING 2020
The use of fertigation for irrigated broad-acre cropping and pastoral farm systems is an emerging technology in New Zealand. Its uptake potentially creates both production and environmental gains – increasing nutrient efficiency and decreasing the risk of leaching and run-off. However, its efficacy, particularly for nitrogen applications, needs to be better understood. In 2019 IrrigationNZ entered into a two year Sustainable Farming Fund project with MPI with the aim of providing answers to the following questions:
• What does ‘good practice’ fertigation management look like?

Recently IrrigationNZ and partners reached a major milestone after establishing the Know Your Catchment dashboard and interface. It is currently focused on the Waitaki area – with the Waitaki Irrigators Collective (which includes five irrigation schemes and a large number of independent irrigators, covering over 75,000 hectares). However, there is scope and plans for it to be extended into other areas.
2018 – 2020 Building Trust is a project which was born in 2018 to educate the public in an informative and engaging way about water quality.
Given the current public feeling around water, this lack of transparency, coupled with limited observable improvements in water quality, will undoubtedly create further issues for farmers and growers.
There are also numerous catchments where much of the environmental monitoring data is not visible, particularly data gathered through resource consents.
Accelerating practice change through better quantifying the benefits and demonstrating peer adoption levels.
The Building Trust project has been funded through MPI Sustainable Food and Fibre Futures Fund and managed by IrrigationNZ in partnership with Waitaki Irrigators Collective, Otago Regional Council, and Environment Canterbury and support from, FAR, Beef+Lamb NZ.

• Refining where environmental ‘hot spots’ are within a catchment
To overcome this, farmers need to openly demonstrate the practice change that is occurring – the tangible actions happening within their catchment to improve water quality. Also, all the robust environmental monitoring data needs to be gathered together to help better show the gains being made over time.

“We really hope people utilise this platform for many years to come and we are currently looking at ways we can extend and maintain it for future use.”
The ongoing limits-setting regime under the Freshwater Manage ment NPS through the new regulatory system has resulted in the adoption of audited Farm Environment Plans and the need to have updated records of water quality parameters. As a result, there is much practice change now happening and it is now well documented. For many catchments with water quality issues, due to the time lags involved with data collection, it takes time to observe the changes.

• Better targeting where support and resources are needed to assist farm practice change
IrrigationNZ CEO Elizabeth Soal said she was excited about this project, both the work that had been completed and the future of it. “This is a game changer in showcasing water quality, not only does it show the important data, it offers an insightful and innovative way to look at it as well as showcasing the people who are championing water and improving the future of water quality.”
The “Building Trust –Telling the Farming Story” project named “Know Your Catchment” recently went live with a visual and engaging interface, under-pinned by a secure data management and analytics system. It has collated all of the above data, dealing with data privacy and sharing issues, analysed and then made it available to both the catchment and wider community – telling the farming story at a catchment scale. This will build trust over time through better informing the community of the commitment farmers are making towards maintaining and improving water quality. Alongside ‘telling the story’, there are other benefits that may arise from improved information on changes in farm practice and water quality monitoring data. These include:

The Morven Glenavy Ikawai Irrigation Company, known as MGI, is responsible for the Redcliffs; Morven, Glenavy, Ikawai; and Waihao Downs Water Schemes. The Redcliffs scheme is one of the oldest in New Zealand, when it was constructed as a depression relief project in the 1930s. The Morven, Glenavy, Ikawai scheme was then built by the Govern ment in the 1970s. MGI purchased the two schemes from the Crown in 1989 and is now responsible for supplying water from the Waitaki river to 28,000 hectares of farmland in SouthMGICanterbury.Environmental Manager Judith Neilson said water sampling was an important part of water quality management for the company, and said it was fundamental it was doneShefrequently.saidevery month in the Waihao Downs Scheme surface water samples were taken from four sites within the scheme’s area, with groundwater sampling occurring during the irrigation season, as well.

One kilometre of track was recently cleared and the plants will be put in the ground throughout the impending spring season. They will be planted three metres either side of the track. Stage three would involve final plantings and track extension to two kilometres to see the project through to its completion.

A desire for people to enjoy the river and create biodiversity on the river’s edge prompted Mrs Strang’s idea for the Clifton Falls Walkway project, an extension of the Kakanui Community Catchment Project which did initial planting of the swimming hole five years ago which was beginning to mature now. Mrs Strang is the project manager and said she wanted to continue this great work.

A passion for planting natives and wanting to encourage people to establish a connection to water sparked an idea for a North Otago farmer.
Work has already begun on the project including clearing some of the track, but there was still plenty more work to come as 2,500 locally sourced plants ranging from harakeke to kowhai have been ordered to plant in the spring. Mrs Strang said the project had been divided into stages and each stage would be funded separately.

For nine years Mrs Cameron has been the secretary of the Waitaki Independent Irrigators Inc., representing 52 properties, which falls under the umbrella of the Waitaki Irrigators Collective (WIC), a collective leading sustainable water planning processes for water users in the catchment, to enable the social and economic development and wellbeing of the Waitaki community.
Mrs Cameron has been involved in providing submissions and evidence to the development of the Canterbury Natural Resources Regional Plan, the (abandoned) Project Aqua hydroelectricity proposal, the Resource Management (Waitaki Catchment) Amendment Bill, the Waitaki Catchment Water Allocation Regional Plan, as well as regional plan change processes.

• Undertaking OVERSEER nutrient budgeting and management
“At Wainui, we hold one Environment Canterbury resource consent (these were several separate permits but have all recently merged into one) to irrigate 510 hectares.” Mrs Cameron said having this permit allowed them to invest in their property in order to increase efficiencies.
• All irrigation infrastructure is to be tested on a regular basis in accordance with the Code of Practice for Irrigation Evaluation
“Farming can be very complex, there are a lot of variables across the regions, and issues in the Waitaki catchment can be very different to elsewhere.”Althoughthese processes have been difficult at times and have involved some head scratching moments, Mrs Cameron said they have created a focus on the health of water and ecosystems.“Animalhealth is a big focus for us, always has been, and so is the environment, if you don’t look after your land you can’t look after your animals properly, they go hand in hand.”
• Implementing a Farm Environment Plan, which is audited on an annual basis, and must implement mandatory good management practices across the property
“These investments are not made lightly. We know our land best and support good management practice. Any uncertainty created through yet further farming restraints increases our exposure to risk (financial) which in turn impacts on our investment decisions, and ultimately impacts the local economy.”Wainuihashad irrigation for over 40 years.
• Developing or maintaining riparian margins and shelter belts
The Camerons’ water permit is subject to the comprehensive suite of water quality conditions now likely to become widespread under the new proposed National Policy Statement for Freshwater Management. In addition, their takes are telemetered, and they are registered on the Environment Canterbury Farm Portal for reporting purposes. Conditions of their water permit include:•Minimum flow restrictions
Over the years they have undertaken extensive fencing of waterways and more recently completed eight kilometres of double fencing, at a cost of $120,000 for labour and materials.MrsCameron said as farmers it was always front of mind of how they could best steward their“Weenvironment.knowwecan’t farm without healthy water and However,land.”from her experiences she feared future generations were at risk of drowning in paperwork.

While the policies in the Plan acknowledged their priority over those seeking to take new water, hearings and subsequent appeals were still required, which were long, complicated processes and it was 2011 before the Cameron’s were finally granted consent renewal.“Understanding the ongoing ins and outs of consenting has required an enormous amount of learning … I have my own copy of the Resource Management Act it’s amazing what you can actually remember when you needSheto.”had also been involved with submitting to provide evidence to the Canterbury Land and Water Regional Plan (fully operative in 2017) and the various Plan changes that have followed, more recently Plan Change 5 and associated nutrient management. “There have now been seven Plan Changes in a period of two years, we no sooner finish submitting to one Plan and another is notified – in many instances before the former has even become operative.

Advice on how to prevent these causes of damage are also included in the guide.MrCantwell said we want to support farmers and growers to use irrigation as part of their operation as we see irrigation as an important part of supporting the growth of strong and prosperous rural communities. “The collaboration of farmers, growers, and other industry partners with IrrigationNZ and FMG helped identify key causes of irrigator damage, both from winds and operational accidents. To continue to help irrigator users throughout the country, we have developed this guide on how to mitigate irrigator risks and minimise the disruption should damage unfortunately occur.”
Advice, Stephen Cantwell said wind accounts for 34 percent of all claims. “Over half of all FMG’s wind damage claims occur in spring. Corner arms are especially susceptible to damage during high winds because of their length and angle. We’ve found that corner arms have also been damaged in up to six percent of wind claims,” said Mr ThroughCantwell.claims insights and alongside IrrigationNZ, FMG has developed a new Irrigation Guide to support farmers and growers to prevent irrigator damage.

Changes to the Resource Management Act to fast track infrastructure projects as part of the COVID-19 recovery have been welcomed by a much-anticipated water storage scheme in Northland.Anewreservoir near Kaikohe which will be available for farmers and growers for irrigation, as well as supporting town water supply for Kaikohe, is set to begin construction this year, the first of 17 infrastructure projects fast tracked under the new legislation.
Previous studies analysed the entire province of Te Tai Tokerau (Northland) and determined the Mid-North and Kaipara were the best places to develop the schemes due to suitable horticultural soils, demand and opportunity due to climatic conditions and significant potential for economic growth of localDevelopmentcommunities.of the scheme in the MidNorth is expected to potentially lift the areas’ GDP by $67 million per year and employment by 12 percent, and in Kaipara GDP could rise by $83 million per year and create a five percent lift in employment. The project also aimed to address disparities in Māori access to water for land development.
Project advisory group member, Terence Brocx, who owns a 200 cow dairy farm near Ohaeawai said there was strong interest in the project from within the wider primary sector in the Mid-North and a belief that there was significant potential to grow high-value horticulture in the region if a reliable source of water was available.
The reservoir is just one in a series which are planned to be built by Te Tai Tokerau Water Trust on the northern Pouto Peninsular in Kaipara and in the Mid-North around Kaikohe. Combined, the water storage and distribution schemes would allow landowners to plan potential land use change with confidence and would support approximately 7,000ha of new horticultural development, an approximate 50 percent increase in Northland’s current area under production.
The Provincial Growth Fund has provided $67.5 for development of the schemes. Construction of the first reservoir called Matawii, near Kaikohe was hoped to begin before the end of 2020. Two others, one each in the Mid-North and Kaipara, are planned to start early in 2021. Water could be available for use as early as summer 2022.
“The whole area is ripe for development because there are top class soils, which along with a desirable climate, has the ability to grow high value crops, but the only thing that is missing is reliable water,” Mr Brocx said.
The scheme will create small scale reservoirs within both regions. These will be filled from natural water catchments during high flows. A network of pipes and pumps will then deliver water under pressure to landowners throughout the areas where water is available. Landowners who wish to have access to water will need to buy shares in the schemes, however final costs have not yet been determined. Development of the full scheme is likely to be over a longer period in response to demand.TheTeTai Tokerau Water Trust (TTTWT) was set up in June 2020 with the responsibility of developing the schemes. Made up of North landers, it is likely the Trust will transition to a private company once the schemes are established.TTWTChairman Murray McCully said while there might have been plenty of rain in Northland over winter there were still problems with water scarcity in the North, and the water storage scheme was a once in a lifetime transformational opportunity for the region.“Youonly have to look to Kerikeri to see what a reliable source of water can do for a community. The success of the horticultural industry there has been largely built on the back of government funded reservoirs which were built in the 1980s. Now it’s time for other areas in Northland to get the same opportunity and we are very thankful for the government support to help us address the issue,” Mr McCully said.
“Either way, the region will benefit from increased investment and economic activity.” IrrigationNZ sits on the project advisory group.

“I’m excited about the prospect of what this water scheme could mean for the community andHeregion.”saidsome landowners would develop their own land, some would diversify part of their property and some would sell to other developers who would be attracted to the region by the security a water scheme would provide for horticultural development.

FLOATING WETLANDS TO MAINTAIN
Renewable energy prospect gets funding boostPresentLakeOnslow
The Government will invest $30 million into investigating a proposed hydro storage scheme at Lake Onslow in the South Island. The concept was developed by Associate Professor Earl Bardsley from the University of Waikato. The system would significantly expand New Zealand’s hydroelectric storage capacity, providing back-up power when other renew able energy sources were running low – a gap currently filled by coal and gas. Dr Bardsley first researched the idea in 2004 after becoming concerned about the use of natural lakes, such as Tekapo and Pukaki, for hydroHestorage.saidasoft-shored, beautiful, natural lake was not really the best place to have seasonal hydro“Sostorage.mymotivation back then was just to look around and find out if we could use pumped storage somewhere else to store water for “Thehydroelectricity.”onlyplacein the country that I could find for large-scale storage was the Onslow basin. It’s a rock basin, so you can have lake water going up and down and it’s not going to erode the Onslowshoreline.”wasanartificial reservoir rather than a natural lake, located in the backcountry east of Roxburgh, Central Otago. Dr Bardsley first published his findings in 2005, and submitted them to the Ministry of Business, Innovation and Employment (MBIE) in 2019 for their discussion document on renewable energy. He learned of the $30 million investigation into his idea when it was announced by Energy and Resources Minister Megan Woods on 26 July“There(2020).aremany facets to the business case for this large project and it is really pleasing to see sufficient funding given for a detailed review,” says Dr Bardsley. Pumped hydro works by capturing and storing water at higher elevation. When there is abundant cheap electricity in the network, water is pumped uphill to a storage lake. When electricity runs low, the water is released back down, with the pumps operating in reverse to generate electricity.

NEXT STEPS
The Government was now undertaking a detailed business case on energy storage solutions before it moves into more technical investigations.“They’regoing to have one year for a business case. They’ve allocated $30 million to that, most of which is likely to be spent on Onslow evaluations. If they pass that, there’s another $70 million already allocated for more geotechnical studies,” said Dr “IfBardsley.Onslow is the selected option two years on, they will make a decision as to whether to go ahead and start building. That’s when something like $4 billion will need to be spent.” While costly to develop, Dr Bardsley said Onslow pumped storage will lead to cheaper power in the long term, because having a large amount of stored energy drives down prices, similar to what we see today when heavy rainfall fills hydro lakes. “It’ll have an enormous impact for many years to come, if they go ahead with it.”
43|SPRING 2020 IRRIGATION NZ NEWS flooded, but Dr Bardsley says there could be solutions to this.
The hydro storage is also useful to buffer the short-term fluctuations of wind power, so the scheme would be in continuous operation, he said. “In fact, having 1000MW of new generating capacity represents an enabling mechanism for new wind power development, by avoiding the risk of wind power fluctuations destabilising the grid,” he says. “The Tiwai point closure gives urgency for constructing Onslow. This is because in a few years, Manapōuri’s hydro power will be added into the grid, increasing the proportion of electricity which is subject to the risk of a dry year.”
“Then even though you expend power to pump water uphill at Onslow, it gives you a net power gain for the system overall.”
He said Onslow could take some of the seasonal energy storage burden away from Lakes Pukaki and Tekapo, meaning they were less likely to overflow and cause flooding from major rainThatevents.overflow also represents a lost opportunity to generate electricity, which can be reduced by having Onslow store much of the energy instead.
“And perhaps we could then have more wetlands area than we hadFloatingbefore.”
“One of the requirements of the business case is that investigations be carried out on options for generating net ecological gains.” Dr Bardsley, suggested that Onslow’s wetlands could be transplanted onto an artificial floating structure, which would then move up and down with the lake level.
wetlands are currently used on a small scale around New Zealand to absorb nutrients and improve water quality; in Australia they have been used to create habitats for endangered species.
A SOLUTION TO THE ‘DRY YEAR PROBLEM’ AND MORE Hydro storage is particularly important for dry years, when there is not enough rainfall for hydroelectric generators to meet electricity demand. “But it’s not going to just sit there, evaporating away, waiting for a dry year to come along – that would not be economical,” said Dr Bardsley.

New Zealand is one of the few countries in the world with plenty of freshwater available. However to capture the benefit of this valuable natural resource more water storage facilities are Newrequired.Zealand is already well connected with Asia from both a geographical and trade perspective. We are well positioned to benefit from the elevated levels of economic growth this region is experiencing relative to the rest of the world. Even in the subdued economic environment China’s economic is expected to grow this year. The IMF has forecast the economies of emerging and developing Asia will contract by just 0.8 percent in 2020 compared to the global average growth rate of -4.9 percent. Asian consumers are highly conscious of food safety and quality. As average incomes in these regions grow so will their demand for high quality imported food. Irrigation provides an opportunity for New Zealand to increase productivity levels and allows more diverse uses of land. Irrigation is also a tool that can be used to manage weather and climatic risks and therefore also mitigate financial risks.

Irrigation by type in New Zealand. (Source: StatsNZ) when market prices are typically low, or cut short the milk production season. Intensification of systems, whether due to irrigation or not, can result in a higher nutrient loading, coming either directly from the extra livestock being carried or from increased use of fertilisers. However, irrigation done well reduces nitrogen run-off, by ensuring that the water is delivered to dissolve the fertiliser at precisely the time that the plant requires it and is able to absorb it. If rain is forecast on dryland pasture, fertiliser is spread, but then the rain doesn’t arrive, that fertiliser will dissolve at some later date which may not be the optimal time for the plant to adsorb it. Too much rain and/or a lack of uptake by the plant and the nutrients will leach through the soil into waterways.
Irrigation has a role to play in enabling alternative land uses. The ability to apply water when required means land can sustain a wider range of enterprises, particularly more intense arable and horticultural uses. Without access to water it would be too risky to invest in a number of these higher-value crops. Some crops don’t require a large quantity of water, relative to pastures, but they do require water at strategic times.

Our farming and orchard management systems are becoming increasingly complex and sophisticated, including our irrigation systems. Water and nutrients are increasingly being applied in a more precise manner based on soil data readings and/or sophisticated modelling. The need to place water more efficiently onto the land, and in a more automated way, is reflected in the move away from flood irrigation to pivot irrigators.
September–November 2020 air pressure is forecast to be higher than normal to the east and lower than normal to the northwest of New Zealand. This is expected to be associated with La Niña-like north-easterly air flow anomalies. The probability for oceanic La Niña conditions is 57 percent. The majority of NIWA’s criteria for “La Niña Alert” have now been met, including increased trade winds in the equatorial Pacific, an atmospheric response that is La Niña-like, and an expectation for these conditions to continue. This is consistent with other international agencies. New Zealand’s coastal water temperatures are well above average for the time of year and are expected to have an upward influence on air temperatures through spring. Air temperatures are most likely to be above average in all regions of New Zealand. Cold snaps and frosts can be expected in typically colder locations early in the season. Rainfall is about equally likely to be near normal or above normal in the north of the North Island, most likely to be near normal in the east of the North Island, and about equally likely to be near normal or below normal in all other regions. North-easterly winds are expected to continue to leave northern areas, such as Northland, the Coromandel Peninsula, and the East Cape, exposed to sub-tropical rain storms while interior and western areas of the both islands remain sheltered from moisture, particularly in South Canterbury, Otago, the West Coast, and Southland. Soil moisture levels are most likely to be below normal in the west and east of the South Island with river flows in the east most likely to be below normal. Near normal soil moisture levels

• Soil moisture levels are most likely to be below normal (45% chance) while river flows are about equally likely to be near normal (40% chance) or below normal (45% chance).
• Rainfall totals are about equally likely to be near normal (35% chance) or below normal (40% chance).
• Soil moisture levels and river flows are most likely to be below normal (50% chance).
• Temperatures are most likely to be above average (50% chance).
• Temperatures are very likely to be above average (60% chance).
Probabilities are assigned in three categories: above average, near average, and below average. In the absence of any forecast guidance there would be an equal likelihood (33% chance) of the outcome being in any one of the three categories. Forecast information from local and global guidance models is used to indicate the deviation from equal chance expected for the coming three-month period.

3D aquifer mapping – data an asset to community
Cutting edge scientific information is soon going to be available thanks to the 3D aquifer mapping project in the Hawke’s Bay.
The council is leading and co-funding a package of four freshwater security initiatives, in partnership with the Government’s Provincial Growth Fund. These are the 3D Aquifer Mapping Project and whole region freshwater assessment which are underway, and investigations into a Heretaunga flow maintenance/water storage initiative. Going forward the council is in the process of getting quotes for telescopic drilling to 300 metres and planning locations to undertake this drilling which is set to be completed by July 2021. This will be used to validate the SkyTem data. Investigations are also underway looking at the best options for making data and models readily accessible and have developed a prototype system for user-testing.

This Bill comprises a significant part of the Government’s response to the inquiry report and is modelled on the core fundamental principles of drinking water safety as identified by the Inquiry.
• Multiple barriers against contamination of drinking water must be maintained.
Up to 5,500 people were ill as a result and four people are thought to have died from associated causes.
• A high standard of care must be embraced in relation to drinking water
The Three Waters Review is a cross-government initiative led by the Minister of Local Government. Other involved agencies and portfolios include: Health, Environment, Finance, Business Innovation and Employment, Commerce and Consumer Affairs, Primary Industries, Climate Change, Infrastructure, Civil Defence and Emergency Manage ment, Housing and Urban Development, Transport, Conservation, and RuralTheCommunities.Review,began in mid-2017, ran in parallel to the latter stages of the Government Inquiry into Havelock North Drinking Water, which was set up following the campylobacter outbreak in 2016.
• The protection of source water is of paramount importance.
IrrigationNZ believes Government investment in the water sector is a step in the right direction – but calls for a broader strategy to encompass all water infrastructure, including storage and policy development.
In late July, the Government introduced legislation as part of the three waters regulatory reform to Parliament to transform drinking water safety in New Zealand and improve environmental outcomes for our wastewater and stormwater networks.
IrrigationNZ has been advocating for some time for the need for New Zealand to develop an overarching water strategy to guide our planning at the national and regional levels.
“While we are seeing a focus on water from across various policy areas such as the primary sector’s Fit for a Better World, the Essential Freshwater policy package, the creation of the drinking water authority Taumata Arowai and now water services delivery – we are yet to see a joined up approach. This will be particularly important if we are to have a national conversation about water allocation and are to address the still unresolved issue of Māori rights and interests in freshwater.”“Intermsof today’s announcement, the Government has also signalled incentive funding for rural drinking water supplies. The irrigation sector already owns some of this infrastructure and we look forward to working with the Government on this,” said Ms Soal.
In early July, Prime Minister Jacinda Ardern and Local Government Minister Nanaia Mahuta announced the Government will invest $761 million as part of the three waters infastrucuture stimulus package, for a much-needed upgrade to water services across the country.
The Government is reviewing how to improve the regulation and supply arrangements of drinking water, wastewater, and stormwater (three waters) to better support New Zealand’s prosperity, health, safety, and environment. Most three waters assets and services, but not all, are owned and delivered by local councils.

• Water contamination is almost always preceded by change and these changes must never be ignored.
• A preventative risk management approach must be applied in relation to drinking water.
These include:
• Suppliers must guarantee the safety of drinking water; and
Three waters need to be handled with a joint approach to all water management
IrrigationNZ Chief Executive Elizabeth Soal said the proposal to reform water service delivery into large-scale multi-regional providers (for drinking water, wastewater, and stormwater) will provide greater opportunities for investment in water infrastructure (such as water storage) that will improve outcomes beyond three waters, to include water for irrigation, reallocation, and the environment.
The initial findings of the Review were consistent with many of the Havelock North Inquiry’s findings and raised broader questions about the effectiveness of the regulatory regime for the three waters, and the capability and sustainability of water service providers.
“Small local authorities have been constrained from large-scale investments due to restrictions on their borrowing ability, smaller balance sheets, and small rating bases. An amalgamated model could facilitate borrowing for larger water projects.”
