Notice of Requirement for Alteration to Designation: Retaining Wall 603 (Unitec)
1. Introduction
The New Zealand Transport Agency (NZ Transport Agency) gives notice of a requirement to alter a
designation under Section 181(1) of the Resource Management Act 1991 (the RMA or the Act). The
notice is set out in the prescribed forms contained in Appendix A.
The alteration of the designation is required to enable the widening of State Highway 16 (SH16) as
part of the Waterview Connection Project. Two additional areas of land measuring 3m2 and 65m2
are required to accommodate the construction of a new retaining wall adjoining the site at 1
Carrington Road, Mt Albert.
This notice can be considered as a minor Alteration to the Designation in accordance with Section
181(3) of the RMA which provides that:
“A territorial authority may at any time alter a designation in its district plan or a requirement in
its proposed district plan if—
(a) the alteration—
(i) involves no more than a minor change to the effects on the environment associated with
the use or proposed use of land or any water concerned; or
(ii) involves only minor changes or adjustments to the boundaries of the designation or
requirement; and
(b) written notice of the proposed alteration has been given to every owner or occupier of the
land directly affected and those owners or occupiers agree with the alteration; and
(c) both the territorial authority and the requiring authority agree with the alteration—
and sections 168 to 179 shall not apply to any such alteration.”
In regards to (a), Sections 5 and 4 confirm that the alteration involves no more than a minor change
to the effects on the environment and involves only a minor adjustments to the boundaries of the
designation.
In regards to (b), written notice of the proposed alteration has been given to the Unitec Institute of
Technology (Unitec) as the directly affected landowner and Unitec agree with the alteration. Their
written agreement is contained in Appendix B.
In regards to (c), as the requiring authority the NZ Transport Agency agree with the alteration.
2. The Designation
The designation is identified in the Operative Auckland City District Plan: Isthmus Section (1999) as:
“A07-01E Motorway: Western Ring Route - Waterview Connection, Alteration to Designation
A07-01 SH16 between Great North Road and St Lukes Interchange”
The designation is shown on Auckland City Council District Plan Map D04, Planning Map No.2
contained in Appendix C.
The NZ Transport Agency is the Requiring Authority for the designation.

3. The Site to which the Requirement Applies
The land is legally described as Lot 5 DP 314949. It is bounded by Carrington Road on the eastern
boundary and SH16 on the northern boundary.
The location of site is shown on plan DG-GK-3211 contained in Appendix D.
4.
The Nature of the Proposed Work
As part of the Waterview Connection Project, SH16 is to be widened between Carrington Road and
the Great North Road off-ramp. This widening necessitates the removal of the existing retaining wall
adjoining the Unitec campus site at 1 Carrington Road, Mt Albert. A new retaining wall (referred to
as Retaining Wall 603) will be constructed approximately 4 metres from the existing retaining wall.
The location of the new retaining wall is determined by the necessary safe sight distances and
visibility for traffic on the SH16 west-bound to SH20 south-bound ramp of the Great North Road
Interchange.
Two additional areas of land measuring 3m2 and 65m2 are required to accommodate the widening of
SH16 and construction of the new retaining wall. The alteration is limited to these two areas of land,
being a total of 68m2. Figure 1 shows the location of the affected land and the existing designation
and Appendix D contains the land requirement plan.

In addition to these two areas of land, the construction of the retaining wall also requires sub
surface soil nails encroaching into Unitec owned land. These are shown as the red and yellow lines
in Figure 1. The NZ Transport Agency and Unitec are currently negotiating an easement for the soil
nails.
5.
The Effects on the Environment
The effects of the retaining wall construction and motorway operation in this area were considered
in depth in the assessment of effects prepared by the NZ Transport Agency (dated August 2010) and
the subsequent Board of Inquiry into the New Zealand Transport Agency Waterview Connection
Proposal in 2011. Altering the boundaries of the designation to incorporate the two small additional
areas of land results in no more than a minor change to these effects and does not necessitate any
change of conditions of the designation.
As a result of the alteration to the designation, two sections of the existing basalt stone wall
measuring approximately 5 metres and 70 metres need to be removed and rebuilt on the new legal
boundary (being also the proposed designation boundary).
Those parts of the stone wall that are located within the Unitec site are included in the Auckland City
District Plan scheduled area for the former Carrington Hospital Building (ACC Map 2, D04-01) which
includes the main building and site surrounds. Within the Plan, ‘Site Surrounds’ means - “all that
land between the building and the site boundaries to the north (motorway) east (Carrington Road)
and west site boundaries…”
Consultation has been undertaken with the New Zealand Historic Places Trust (NZHPT) to ascertain
whether the stone wall has any specific historic importance. The NZHPT has confirmed that the wall
appears to be of late 20th Century origin and is not a heritage item. Reviews of historical aerial
photographs for the area indicate that the stone wall did not exist in this location prior to the
construction of the motorway in the 1960s. This section of the motorway was also widened in the
early 1980’s and the stone wall was also altered at that time to accommodate those works.
Given that the stone wall is of 20th century origin and therefore is not a heritage/ archaeological
feature, the NZHPT has confirmed that an application for an authority under the Historic Places Act
is not be required for the relocation of the stone wall.
The two affected sections of the stone wall will be removed to a stockpile prior to the adjacent
motorway retaining wall works commencing. The wall will be rebuilt on the new site boundary once
the initial soil nails and capping beam have been constructed. This is expected to be in June 2014).
A specialist stone mason has been engaged to undertake the stone wall reconstruction works.
The NZ Transport Agency (via the Well-Connected Alliance) has been in discussions with Unitec
regarding the stone wall relocation and reconstruction. These discussions have covered the form of
the final wall, the likely construction programme, construction access and construction effects. The
certified Construction Environmental Management Plan (Rev 4 Certified February 2013) sets out the
measures proposed for managing effects during construction including noise, traffic, and
communication.

6.
Alternative Sites, Routes and Methods
During detailed design of the retaining wall, the Well-Connected Alliance have investigated a
number of options to achieve the necessary safe sight distances and better visibility for vehicles on
SH16 which would avoid additional land acquisition. Based on the geometric safety audits
undertaken by the NZ Transport Agency, the proposed design is the only option which achieves full
compliance for safe site distance on SH16. All alternatives within the existing designation result in
compromises for safe site distances and are therefore not acceptable to the NZ Transport Agency.
Therefore there are no acceptable alternative sites, routes and methods to achieve the widening of
SH16 in this location.
7.
Objectives of the Requiring Authority
The widening of SH16, to provide for the new Great North Road Interchange, necessitates the
removal of the existing motorway retaining wall and construction of a new section of retaining wall.
Two additional areas of land are required to accommodate the widening where the new retaining
wall cannot fit within the existing designation. The new retaining wall has been designed to achieve
the necessary safe sight distances and better visibility for vehicles travelling on the SH16 exiting to
the Great North Road westbound off-ramp and the southbound ramp to the SH20 tunnel.
The NZTA cannot achieve the necessary safe sight distances within the existing designation and
therefore seek an alteration to include the two additional areas of land.
8.
Consultation
Consultation has been undertaken with representatives of the directly affected landowner, Unitec.
The NZTA and Unitec are engaged in negotiations for the purchase of the affected property. As the
only directly affected landowner, Unitec has provided its written agreement to the alteration. This
agreement is contained in Appendix B.
Consultation has also been undertaken with the NZHPT to ascertain whether the basalt stone wall
on the existing property boundary is of historic importance. As noted in Section 5, the NZHPT have
confirmed that the wall is not an archaeological feature under the Historic Places Act 1991.
No other parties are considered likely to be affected by this alteration. Notwithstanding this, regular
and ongoing consultation with the community and other stakeholders is part of the existing
designation conditions.
9.
Conclusion
This notice of a requirement to alter a designation has been prepared in accordance with Section
181(3) of the RMA for the addition of two areas of land measuring 3m2 and 65m2 at 1 Carrington
Road, Mt Albert. The alteration of the designation is required to achieve the objectives of the NZ
Transport Agency and enable the widening of SH16 as part of the Waterview Connection Project.
