Historic Character Delivery Work Plan (Archaeology Section)
1. Introduction The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line in the vicinity of Mt Eden Station. The CRL also involves the construction of two new underground stations at Aotea and Karangahape and the redeveloped Mt Eden Station (refer to Figure 1-1). The design and construction of the CRL infrastructure between the Aotea and Mt Eden Stations is being delivered by the Link Alliance.
Figure 1-1: CRL Route and Location
This Historic Character Delivery Work Plan (HC DWP) (Archaeology Section) has been prepared in relation to construction of the new Karangahape Station.
1.1 Karangahape Station The Karangahape Station consists of two entrances, one at Beresford Square / Pitt Street and the other at Mercury Lane, linked together by platforms with two mined tunnels approximately 32m below Pitt Street. The Station will also comprise equipment rooms, ventilation systems and emergency egress at both Mercury Lane and Beresford Square / Pitt Street. Given the nature and scale of the Karangahape Station construction, works will be undertaken in a staged manner, involving:
Page 5
Early works (demolition, network utility relocation and site establishment works) – to be undertaken from October 2019 through to early 2020; Main construction works (construction of the station and mined tunnels for the rail tracks) – to be undertaken from early 2020 through to late 2023; and Public realm reinstatement – likely to be undertaken from late 2022 to late 2024.

Historic Character Delivery Work Plan (Archaeology Section)
1.2 DWP Staging To reflect the staged construction approach for the Karangahape Station, development of this HC DWP (Archaeology Section) will be undertaken in stages. This HC DWP addresses the archaeological aspects of the Karangahape Station early works. The early works are detailed in the Construction Environmental Management Plan (CEMP), and summarised in Section 2 of this DWP. HC DWPs will also be prepared for the main construction works and the public realm reinstatement.
1.3 Purpose of the Historic Character DWP (Archaeology Section) This HC DWP (Archaeology Section) has been prepared to identify measures that will be implemented to mitigate and manage potential adverse effects on archaeology during construction of the Karangahape Station early works. The objective of the HC DWP in accordance with CRL designation Condition 42.2 is:
“To avoid, remedy or mitigate adverse effects on archaeological remains during construction, as far as is reasonably practicable.”
This Archaeology Section addresses the requirements of CRL designation Condition 42 and will be implemented throughout the construction period. The Archaeology Section is consistent with the archaeological provisions of the Heritage New Zealand Pouhere Taonga Act 2014 and the archaeological Authority granted by Heritage New Zealand Pouhere Taonga authorising modification of archaeological sites within the Karangahape Station early works project area (2017/793 – refer Appendix A). This HC DWP (Archaeology Section) has been developed to enable consultation with and feedback from the Karangahape Community and Business Liaison Group (CLG); and review by the Independent Peer Reviewer (IPR) prior to submission to Auckland Council (as per designation Conditions 7 and 11, and resource consent Condition 19). A record of consultation outcomes is included in Appendix C. The HC DWP (Archaeology Section) has been prepared by Clough & Associates Ltd and forms part of the CEMP for the early works. The Built Heritage DWP (Archaeology Section) has been prepared to address the requirements of Condition 41 of the CRL designation.

Karangahape Early Works 2.1 Overview of Works
Early works will be undertaken to establish the site of the new Karangahape Station in advance of the main construction works. The early works are detailed in the CEMP with an overview provided in Table 2-1. Table 2-1: Overview of Karangahape Early Works
Works location
Overview of construction activities
Beresford Square / Pitt Street
Relocation of network utilities located within the footprint of the new Karangahape Station in Beresford Square / Pitt Street; Removal of street trees and the demolition of the café / toilet in Beresford Square; Establishment of the Beresford Square Construction Support Area to provide site offices, construction vehicle parking, laydown areas and storage of plant and equipment etc.; and Closure of Beresford Square to vehicle traffic (other than construction traffic) while retaining pedestrian and cycle access. Removal of existing street furniture where required (such as seating, street lighting (to be replaced with temporary lighting).
Mercury Lane
Relocation of network utilities located within the footprint of the new Karangahape Station in Mercury Lane; and Establishment of the Mercury Lane Construction Support Area within to provide site offices, construction vehicle parking, laydown areas and storage of plant and equipment etc. Establishment of the Mercury Lane working platform.
It should be noted that the demolition of buildings and above ground structures within the Mercury Lane Construction Support Area is authorised by the CRL Enabling Work Outline Plan – Karangahape Road Demolition Works (Council reference OPW60339200), confirmed by Auckland Council in June 2019 and do not form part of this HC DWP.

Historic Heritage Values – Archaeology 3.1 Archaeological Sites in the Project Area
No archaeological sites have been identified within the wider Karangahape Station project area. However, a house and a Sunday school were located in the Beresford Square Construction Support Area (CSA) in the 19th and early 20th centuries, which may have associated subsurface remains. The only other area of potential archaeological interest is the properties at 9A, 9B, 9C, 11-13 and 17-21 Mercury Lane, which are known to have contained buildings during the 19th to mid-20th century. It is possible that 19th and early 20th century archaeological remains may be present subsurface on these properties. The site of the former house and Sunday school in Beresford Square will be affected by the early works (through establishment of the Beresford Square CSA). In addition, the properties at 9-23 Mercury Lane and 20 East Street will be affected by the creation of working platforms within the Mercury Lane CSA which may expose or uncover archaeological remains. The remaining works will be located within the road reserve of Mercury Lane, Pitt Street and Beresford Square. Within the road reserves, there is only limited potential for impacting on subsurface pre-1900 archaeological remains or significant 20th century historic heritage remains, although the possibility of encountering early drainage infrastructure or earlier street surfaces cannot be excluded. The possibility that subsurface pre-1900 or early 20th century archaeological remains may be exposed during the early works will be managed through the implementation of this HC DWP (Archaeology Section) and an Archaeological Authority (no. 2017/793) granted by Heritage New Zealand Pouhere Taonga (HNZPT) for the wider CRL Project (see Appendix A).

4. Roles and Responsibilities 4.1 Project Archaeologist Roles and Responsibilities The Project Archaeologist will be responsible for ensuring that the archaeological requirements set out in this HC DWP and in the Heritage New Zealand Pouhere Taonga Act 2014 (HNZPTA) authority are fulfilled. This includes ensuring that an archaeologist is available to monitor earthworks where required and respond to call-in by the Link Alliance construction team if any suspected archaeological remains are exposed. It also includes preparation of a Site Specific Safety Plan and ensuring that the archaeological team adheres to the construction team’s site safety requirements. The Project Archaeologist will also be responsible for reporting to the relevant parties as outlined in this section regarding the archaeological work.
4.2 Contractor Briefing Prior to the start of early works (including works within the Beresford Square CSA), the Project Archaeologist and Mana Whenua representatives will meet with the Link Alliance (and contractor(s)) on site to brief them on the archaeological and cultural requirements for the works. The Project Archaeologist must be given at least two weeks’ notice by the Link Alliance that works are about to begin. The Alliance shall keep the Project Archaeologist informed as to the work schedule and any changes that may arise. As set out in sections 6.3, 6.4 and 6.6 of this HC DWP, the Link Alliance will temporarily cease works and call-in the Project Archaeologist if suspected archaeological remains are exposed during works when an archaeologist is not present, so that the remains can be assessed and recorded. As set out in sections 6.4 and 6.8 of this HC DWP, the Link Alliance will give the Project Archaeologist sufficient time and opportunity for the recording and sampling of any archaeological features or deposits encountered, and will not resume clearance works in the immediate vicinity until the archaeological work is completed.

5. Training 5.1 Pre-Construction Briefing Prior to the start of works, the Project Archaeologist will provide a briefing on the archaeological requirements contained within this Archaeology Section of the HC DWP to the Link Alliance and all staff working on the project. These requirements include but are not limited to:
Statutory requirements under the HNZPTA; How to recognise archaeological material (of pre-1900 or early 20th century date) if exposed during excavation works; What actions need to be taken should any archaeological material or remains be exposed or encountered; and Who to contact in the event of archaeological material being exposed, if the Project Archaeologist is not present on site at the time.
Mana Whenua representatives will also be invited to provide a briefing on cultural requirements in case archaeological remains relating to Māori occupation are exposed during the works.
5.2 Toolbox Talks The Project Archaeologist will attend toolbox meetings as required during the course of the works, the purpose of which will be to remind staff of the project archaeological requirements and to ensure that any new staff joining the project team are fully briefed prior to the commencement of works.
5.3 Training Records A record of attendance at briefing and training sessions will be held by the Environmental and Sustainability Manager as part of the project training record (refer to the CEMP for further detail in this regard).

Historic Character Delivery Work Plan (Archaeology Section)
6. Archaeological Procedures and Mitigation Measures 6.1 Beresford Square CSA An archaeologist will be present to monitor any excavations within the Beresford Square CSA (such as excavation to establish the settlement pond or other purposes), in case any subsurface archaeological features relating to the former house and Sunday school are present. If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed, they will be investigated, sampled and recorded by the archaeologist.
6.2 Mercury Lane CSA An archaeologist will be present to monitor any excavations or surface clearance within the properties at 9-21 Mercury Lane. If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed, they will be investigated, sampled and recorded by the archaeologist.
6.3 Archaeology Discovery Protocols As noted in Section 3.1, there is only limited potential for subsurface archaeological remains to be exposed elsewhere during the early works, which apart from the Beresford Square and Mercury Lane CSAs, will be limited the road reserves. However, the possibility that archaeological features and deposits may be exposed during works will be managed and mitigated by call-in by the construction team; the recording of any remains exposed; and the recovery of samples of archaeological material for further analysis. If suspected archaeological remains (of pre-1900 or early 20th century date) are encountered, works will stop in the immediate vicinity of the find until the Project Archaeologist can assess the site.
6.4 Discovery of Archaeological or Cultural Remains If in situ archaeological features or deposits (of pre-1900 or early 20th century date) are identified during the early works, the Project Archaeologist will stop works in the immediate vicinity by notifying the Karangahape Station Project Manager or the Karangahape Station Construction Manager and will investigate and record the remains, in accordance with accepted archaeological practice as set out in this HC DWP and the requirements of the HNZPT Authority. If remains indicating MÄ ori occupation are exposed the protocols outlined in Section 6.5 of this HC DWP will be followed. If significant archaeological features or deposits are identified during clearance works the Auckland Council (Cultural Heritage Implementation Team Leader and Compliance Monitoring Officer), HNZPT, and Mana Whenua will first be notified by the Project Archaeologist, and the remains will then be investigated and recorded in accordance with accepted archaeological practice and as directed by HNZPT, if of pre-1900 date. Any significant remains of 20th century date will also be investigated and recorded as directed by the Auckland Council Cultural Heritage Implementation Team Leader.

Historic Character Delivery Work Plan (Archaeology Section)
6.5 Mana Whenua Protocols 6.5.1. Archaeological Remains If archaeological remains relating to Māori occupation are exposed, the Project Archaeologist will inform the appropriate Mana Whenua representatives.
6.5.2. Kōiwi Tangata (Human Remains) If bone material is identified that could potentially be human, the following protocol will be adopted:
Earthworks/investigation will cease in the immediate vicinity while an archaeologist establishes whether the bone is human; If it is not clear whether the bone is human, work shall cease in the immediate vicinity until the Auckland University reference collection and/or a specialist can be consulted and a definite identification made; If bone is confirmed as human (kōiwi tangata), the archaeologist will immediately contact the Mana Whenua representatives, HNZPT, the NZ Police Auckland Central crime squad and Auckland Council Cultural Heritage Implementation Team Leader and Compliance and Monitoring officer; The site will be secured in a way that protects the kōiwi as far as possible from further damage; Once the NZ Police and HNZPT are satisfied that the remains are archaeological, consultation will be undertaken between the Mana Whenua representatives, the HNZPT Regional Archaeologist, the Auckland Council Cultural Heritage Implementation Team and CRLL to determine and advise the most appropriate course of action. No further action will be taken until responses have been received from all parties, and the kōiwi will not be removed until advised by HNZPT; The Mana Whenua representatives will advise on appropriate tikanga and be given the opportunity to conduct any cultural ceremonies that are appropriate; If the Mana Whenua representatives are in agreement and so request, the bones may be further analysed by a skilled bio-anthropological specialist prior to reburial, in line with the HNZPT Guidelines Kōiwi Tangata Human Remains (2010); and Activity in that place can recommence as soon the bones have been reinterred or removed and authorisation has been obtained from HNZPT.
6.5.3. Taonga (Māori Artefacts) Māori artefacts such as carvings, stone adzes, and greenstone objects are considered to be taonga (treasures). These are taonga tūturu within the meaning of the Protected Objects Act 1975. Taonga may be discovered in isolated contexts but are generally found within archaeological sites. If taonga are discovered the following protocols will be adopted:
Page 15
The area containing the taonga will be secured in a way that protects the taonga as far as possible from further damage, consistent with conditions of the Archaeological Authority (no. 2017/793); The Project Archaeologist will then inform HNZPT, Auckland Council and the nominated Mana Whenua representatives so that the appropriate actions (from cultural and archaeological perspectives) can be determined; | Karangahape Station Early Works
Historic Character Delivery Work Plan (Archaeology Section)
These actions will be carried out within the stand down period specified below, and work may resume at the end of this period or earlier if advised by HNZPT or the Project Archaeologist; The Project Archaeologist will notify the Ministry for Culture and Heritage of the find within 28 days as required under the Protected Objects Act 1975. This can be done through the Auckland War Memorial Museum; and The Ministry for Culture and Heritage, in consultation with Mana Whenua, will decide on custodianship of the taonga. If the taonga requires conservation treatment (stabilisation), this can be carried out by the Department of Anthropology, University of Auckland (09-3737999) and would be paid for by the Ministry. It would then be returned to the custodian or museum.
6.6 Recording of Features and Deposits Any in situ pre-1900 or significant 20th century archaeological deposits or features exposed during the early works will be investigated, recorded and sampled consistent with accepted archaeological practice as set out in this DWP and in accordance with the requirements of the HNZPT Authority (No. 2017/793). Detailed notes of each feature and deposit will be made, photographs will be taken, and all subsurface features located will be detailed on the site plan. Stratigraphic drawings and photographs of features and deposits will be undertaken. Sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered. The archaeologist(s) will record the archaeological feature(s) or deposit(s) as quickly as possible so that works may resume without undue delay.
6.7 Artefact Management Plan The locations of artefact deposits will be marked on the site plan and retained for analysis. If large numbers of artefacts relating to European occupation are exposed, a representative sample will be retained. The process for storage, analysis and display shall be as follows:
Artefacts will be bagged, labelled by date and context, and may initially be stored in a secure on-site lock-up facility provided by the contractor; As soon as is feasible, artefacts will be transferred to the Project Archaeologist’s offices for cleaning, recording and analysis; Any significant artefacts and/or artefacts meriting public display, will be identified by the Project Archaeologist and, in consultation with the relevant stakeholders, will be considered either for display within the new Karangahape Station or for donation to the Auckland War Memorial Museum, as appropriate; Less significant finds will be disposed of following recording and analysis, subject to CRLL agreement, unless a museum is willing to accept the collection; and Any wooden or fibre artefacts of significance will be wrapped/contained as required for short term preservation and analysis.
Artefacts will be conserved by appropriate specialists if this is recommended by the Project Archaeologist based on the level of significance and suitability for display or addition to museum collections. Page 16
| Karangahape Station Early Works
Historic Character Delivery Work Plan (Archaeology Section) Any Māori artefacts that meet the criteria of taonga tūturu under the Protected Objects Act 1975 will in addition be managed as set out under the Mana Whenua Protocols (Section 6.5.3 of this DWP).
6.8 Stand Down Periods Depending on what is revealed by the clearance works, stand down periods involving the ceasing of works in the immediate vicinity may be required at various stages to allow for archaeological work to be carried out or for consultation with the appropriate parties. Stand down will require clearance works to cease only in the immediate vicinity of the feature or find, and work may proceed in other areas. The maximum stand down periods in Table 6-1 will apply but works may be resumed earlier if the required work has been completed. Timeframes need to be flexible enough to ensure that archaeological works are completed as necessary to ensure that the procedures in this HC DWP and the conditions of the Archaeological Authority (no. 2017/793) are met.

Maximum 2 days in each location, but work may continue in areas where no remains are identified.
Sufficient time must be allowed for the archaeologist to investigate and record the remains.
Work resumes when the Project Archaeologist advises the site foreman that work is completed.
Significant archaeological feature, deposit or artefacts, or significant 20th century historic heritage remains, that were not anticipated
Up to three days for a response from HNZPT for pre-1900 remains, and in most circumstances up to three days for any detailed investigation required. Up to three days for a response from Council if significant post-1900 historic heritage remains are found, and up to three days for any detailed investigation required.
The likely requirement is a mitigation investigation and/or recording by standard archaeological techniques, but this will be advised by HNZPT, or by Auckland Council if the find is of 20th century date. Note that there may be special circumstances in which a longer period of stand down for investigation is deemed necessary by either HNZPT or Auckland Council.
Work resumes when the Project Archaeologist (and the Council’s Compliance Monitoring Officer in the case of post-1900 remains) advises the site foreman that work is completed.
Human bone found
As agreed between the project manager, HNZPT, Auckland Council and Mana Whenua.
HNZPT and NZ Police to be satisfied that kōiwi identification is correct. Mana Whenua representative(s) to organise reinternment or removal of bones from site and appropriate cultural ceremonies.
Work resumes following reinternment or removal of bones from site and when authorisation from HNZPT and the Council’s Compliance Monitoring Officer has been received.

6.9 Post Excavation Analysis and Archiving Artefacts and faunal material retained from the site will be analysed and recorded by the appropriate specialists with the results presented in the final archaeological report, which will be provided to the parties specified in Section 6.10 of this HC DWP for information and archiving. Depending on what is exposed, consideration will be given to displaying archaeological material such as artefacts within the new Karangahape Station. Any artefacts of significance relating to European occupation of the area that are recovered from the site that are not required for display may be offered to the Auckland Museum in consultation with the Link Alliance. Any Māori artefacts (taonga tūturu) will be dealt with in accordance with the Mana Whenua protocols outlined in Section 6.5 of this HC DWP and the requirements of the Protected Objects Act 1975. Archaeological material identified by the Project Archaeologist as being appropriate for Carbon 14 dating will be sent to the University of Waikato’s Radiocarbon Dating Laboratory for age determination.
6.10 Reporting Requirements During the course of the project, information on any archaeological discoveries will be provided to the Auckland Council Cultural Heritage Implementation Team and Compliance Monitoring Officer, HNZPT and Mana Whenua. Opportunities for provision of information to the public via on site and media releases will be taken in consultation with those parties, depending on whether any significant archaeology is exposed during earthworks. In compliance with the requirements of HNZPT Authority 2017/793, a written summary report will be provided by the Project Archaeologist to the Link Alliance, HNZPT, Auckland Council (Cultural Heritage Implementation Team and Compliance Monitoring officer) and Mana Whenua within 20 days of the completion of the project works. A full and final monitoring report will be completed within 12 months of the end of the project works, and will be provided to the Link Alliance, HNZPT, the Auckland Council (for inclusion in the Cultural Heritage Inventory), the NZ Archaeological Association Central File, Mana Whenua and any other parties specified in the designation conditions and archaeological Authority. On completion of the final report, the Project Archaeologist will update the archaeological site records on the NZAA Site Recording Scheme (ArchSite database) and

Historic Character Delivery Work Plan (Archaeology Section)
Appendix A: HNZPTA Requirements In addition to the requirements of CRL designation 2500-4, and this HC DWP (Archaeology Section) prepared in accordance with CRL designation condition 42, all modification and investigation of pre1900 archaeological remains are subject to the archaeological provisions of the Heritage New Zealand Pouhere Taonga Act 2014 (HNZPTA) and must be carried out in accordance with the conditions of an Authority issued by HNZPT under that Act. A general Authority for the Aotea Station to Mt Eden Station/NAL works, including modification of any subsurface remains exposed by the Karangahape Station early works including the CSA, has been granted by HNZPT (Authority No. 2017/793). The Authority sets management procedures in place for archaeological discoveries. Care has been taken to ensure that the archaeological procedures set out in this DWP are consistent with the conditions and requirements of the Authority issued by HNZPT.

Appendix C: Record of CLG, IPR and Auckland Council Comments
C1. CLG Comments A Karangahape CLG meeting was held on 17th September to discuss the Karangahape early works and for the CLG to provide comments / feedback on the CEMP and sub-plans, including this HC DWP (Archaeology Section). No comments were received from the CLG on this DWP.
C2. IPR Comments An Independent Peer Review of the draft HC DWP (Archaeology Section) was undertaken by Matthew Campbell, from CFG Heritage. The comments received are as follows: DWP Section

Resolution
-
A table of acronyms should be provided at the start of the document (e.g. CSA)
No changes made. Acronyms have been checked and all are spelled out in full when first used
1.3
Reference to the Built Heritage DWP seems to be redundant.
No change. The two documents together make up the Historic Character DWP and crossreference to each other
3.1 [4.1]
Project Archaeologist roles and responsibilities should outline the legal Health and Safety responsibilities of the project archaeologist and how they fit into the contractor’s and CRLL’s H&S responsibilities and requirements. Under the Health and Safety at Work Act 2015 it is no longer sufficient for a subcontractor to rely on the contractor’s protocols.
Reference to preparation of a Site Specific Safety Plan has been included in section 4.1 of this DWP
6.4 and 6.6
6.4 and 6.6 refer to “accepted archaeological practice as set out in this HC DWP.” Accepted practice is not set out in the DWP, and reference to the DWP in these paragraphs should be deleted. Reference could usefully be made to HNZPT guidelines.
Section 6.6 of the DWP provides a summary of accepted archaeological recording practice and Section 6.7 details accepted archaeological practice in relation to artefacts. No changes have therefore been made to this DWP
6.5.2
Kōiwi tangata should, for clarity, specify “the NZ Police Auckland Central crime squad.”
Section 6.5.2 has been amended to include this more specific reference
6.8
Stand Down Periods. This section states that “timeframes need to be flexible” and section 5.6 states that “sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered.”
No changes have been made, as the contents of Table 6.1 are consistent with the Archaeological Management Plan approved under the Heritage NZ Authority (2017/793) and have been standard for previous Authorities and Heritage Management Plans approved by Council for other projects of this

Comment
Resolution
However, Table 5.1 provides for Maximum Stand Down Periods, which is incompatible with flexible timeframes and sufficient time and opportunity, as well as Condition 3 of HNZPT authority 2017/793, which states that “All archaeological evidence encountered during the exercise of this authority must be investigated, recorded and analysed in accordance with current archaeological practice.” Current archaeological practice is potentially time consuming and, while it is understood that the archaeologist will make very reasonable effort to clear the area as quickly as possible, this may not always be possible within the time frames outlined on Table 6.1. This table also states “Note that there may be special circumstances in which a longer period of stand down for investigation is deemed necessary by either HNZPT or Auckland Council.” This is potentially confusing. I suggest that Table 6.1 be changed to Stand Down Triggers, the second column deleted and the table re-formatted to include relevant HNZPT, Council and mana whenua response times. The Archaeological Management Plan should be also be updated under Condition 1 of authority 2017/793.
type, where extensive archaeological remains are not expected. It is not considered that there is incompatibility between the fact that the contractor’s timeframes need to be flexible, and the minimum stand down periods given, as the necessary flexibility sits within those timeframes. Only limited remains are likely to be encountered during the early works, but a slightly longer stand down period is given for any significant archaeological remains encountered, with appropriate recognition that HNZPT or Council may require a longer period for investigating any significant discoveries.
C3. Auckland Council Comments This draft HC DWP (Archaeology Section) was received from Myfanwy Eaves, Senior Specialist in Historic Character – Archaeology, Auckland Council. Her review contained no specific comments on this Historic Character DWP (Archaeology Section), except to note that in Table 6.1 Maximum Stand Down Periods, if koiwi tangata are discovered works should only resume when authorised by the Council’s Compliance Monitoring officer in addition to HNZPT and the Project Archaeologist. Table 6.1 has been amended to reflect this.
