ISCA-New Zealand Founding Membership

The New Zealand Advisory Group on Infrastructure Sustainability (Advisory Group) has agreed that the best means for New Zealand to advance its infrastructure sustainability agenda is to see if ISCA can broaden its remit to include New Zealand and to establish a New Zealand version of the IS rating tool; similar to how ISCA was established in Australia.

ISCA are therefore inviting New Zealand organisations to become ISCA New Zealand Founding Members. Three organisations have already secured their New Zealand Founding Membership, they are;

  • AECOM New Zealand
  • Auckland Airport
  • BECA
  • Panuku Development Auckland
  • Tonkin & Taylor

ISCA New Zealand Founding Membership fee is $15,000 New Zealand dollars. ISCA New Zealand Founding Members will enjoy:

  • Enduring acknowledgement of leadership through Founding Membership via ISCA and self promotional activities.
  • Opportunities to participate in defining and leading New Zealand infrastructure sustainability priorities.
  • Participating in the development of the New Zealand IS rating tool.
  • Platform to showcase and share infrastructure sustainability thought leadership.
  • Opportunities to engage with suppliers, clients and policy makers across common issues and opportunities.  
  • ISCA event, training and Infrastructure Sustainability rating scheme discounts.

Funds from New Zealand Founding Memberships will be used to establish New Zealand resources, facilitate name and governance transitions, deliver New Zealand member benefits and assist with securing funding to develop the NewZealand version of the IS rating tool.

New Zealand Advisory Group on Infrastructure Sustainability

Representative of the New Zealand Advisory Group on Infrastructure Sustainability are interested in progressing infrastructure sustainability in New Zealand. The group has come together to guide ISCA on:



  • Governance (board representation, changing the name to Australasia or equivalent).
  • Extending membership to New Zealand organisations, including initial Founding Membership.
  • Facilitate New Zealand IS rating tool development and IS ratings through ISCA New Zealand based resources.
  • Delivery of New Zealand IS training through ISCA New Zealand based resources.
  • Identification of key infrastructure sustainability advocacy areas to support long term triple bottom line outcomes.

The New Zealand Advisory Group on Infrastructure Sustainability comprises of:

  • Jim Harland – Regional Manager South NZTA (Chair)
  • David Taylor – National infrastructure Unit
  • John Mauro – Auckland Council
  • Stephen Selwood – NZCID
  • Martin Fryer – Auckland Airport
  • Graham Spargo – BECA
  • Kylie Eltham – Fletchers
  • Leeanne Walters – Fulton Hogan

Engagement and collaboration


ISCA was approached by Panuku Development Auckland, Auckland Transport and Auckland Airport, separately, interested in piloting the IS rating tool in New Zealand. Early industry engagement on the back of this interest resulted in collaborative relationships being established with “The Sustainability Society” (a technical interest group of the Institute of Professional Engineers New Zealand), New Zealand Council for Infrastructure Development (NZCID) and the Institute for Public Works Engineering Australasia (IPWEA). There has also been focused engagement with a number of transport and water infrastructure owner or operators and national government agencies and ministries, which has been informative and very positive.



Some of the stakeholders include:

  • Auckland Airport
  • Auckland Council
  • Auckland Transport
  • Bay of Plenty Regional Council
  • Christchurch City Council
  • Panuku Development Auckland
  • Kiwi Rail
  • Port of Auckland
  • Ministry for Social Development
  • Ministry for Business, Innovation and Employment
  • Ministry for Environment
  • National Infrastructure Unit
  • NZ National Transport Authority
  • Waikato Regional Council
  • Wellington City Council
  • Wellington Water

The NZ IS rating tool

To date the following are registered as New Zealand IS Pilot ratings:

  • City Rail Link – Auckland Transport (Planning / Design rating)
  • Madden and Pakenham West Rd Upgrade – Development Auckland (Design rating)
  • Auckland Airport Operations Pilot – Auckland Airport (Operations rating)
  • Auckland Airport - Phase 3 – Auckland Airport (Planning)

Both the Madden and Pakenham West Rd Upgrade and Auckland Airport Operations Pilot ratings are currently going through the third party verification process, and therefore we look forward to New Zealand’s first certified ratings soon.

In addition to potentially achieving a IS rating, these pilots are inherently assisting with defining what the NZ IS rating tool should comprise. Therefore, the more pilot projects or assets that register at this formative stage in NZ, the more refined, tailored and effective the first formal NZ version of the IS rating tool will be.

Early feedback on the infrastructure sustainability rating tool being applied in New Zealand:

Auckland Airport

“The ISCA rating tool fitted our thinking and approach and therefore we wanted to undertake a pilot rating for operation of airport infrastructure (currently in verification stage). The rating process and associated outputs have already provided a useful gap analysis in the context of identifying  risks and opportunities corporately and across the asset. The process has challenged our approach to asset management and provides an opportunity to embed sustainability into assets at the design stage. The client side self-assessment assists in the preparation of tender documentation and defining suitable targets and objectives. Pursuing a rating sends a clear message to our supply chain around our focus on sustainable development. It is ensures that as our master plan is implemented that sustainable development objectives, targets and outcomes are continuously considered and implemented from planning through to operation of our assets.” Martin Fryer, Sustainability Manager, Auckland Airport

Madden and Pakenham West Rd Upgrade

"We registered this project to demonstrate via a 3rd party verified tool that Waterfront Auckland is committed to meeting the environmental, social and cultural objectives of our Waterfront Plan and Sustainable Development Framework. The major benefit to our project through implementing the IS scheme is it will focus our work practices to deliver better auditing and reporting on a quadruple bottom line standing. It also allows us to communicate to the community that Waterfront Auckland is committed to sustainability in the infrastructure we deliver and are happy to have this rated by an independent body." Ralph Webster, Design Manager, Waterfront Auckland

Piloting the New Zealand IS rating tool



In 2014, industry stakeholders held a workshop with ISCA to scope the changes required. The results of this collaborative exercise are presented in the “New Zealand IS Workshop Development report”.

The scope and industry drivers and objectives for New Zealand IS rating tool have been further evolved through industry engagement over the past 12 months and the current pilots. Key expectations regarding New Zealand IS rating tool include:

  • It must be applicable to projects with a capital value less than one (1) million dollars as well as above, particularly for councils.
  • It must include Maori or Iwi aspects implicitly in the current credits (e.g. biodiversity) and explicitly as standalone categories or credits.
  • It would preferable that workforce, economic and supply chain aspects are incorporated into the first version of the New Zealand IS rating tool and it is complimentary to the New Zealand “Better Business Cases”.
  • It is linked to and supports resilience and natural hazard planning as well as decision making.
  • It must be an effective measurement and data capture tool, to support project and industry decision making.
  • It must be one (1) tool for all infrastructure classes and complementary with other built environment tools or frameworks.
  • It must not promote gold plating, but facilitate good decision making and project or asset efficiency gains.

With some of the first pilots now reaching certification it is an imperative that the valuable leadership, knowledge and lessons learnt are captured and used to inform what the New Zealand IS rating tool should comprise. We are also accepting new New Zealand IS Pilot rating registrations for all asset types (water, transport, precinct, energy, resource, green, civil works) of any scale.

The business case for IS rating scheme

Lessons learnt through application of the IS rating tool in Australia and New Zealand combined with feedback from New Zealand stakeholders reinforced that the IS rating tool can and should be used beyond simply pursuing an industry benchmarked rating. The IS rating process can support an organisation with many of the following outcomes:

  • Corporate target setting and reporting, and on-going activation of internal corporate sustainability strategies and initiatives.
  • Benchmarking the sustainability (triple bottom line) performance of asset networks to inform asset management targets and plans, scorecard reporting and decision-making.
  • Driving cost savings through resource efficiency.
  • Informing the “story” around the performance of your assets and rationale for new projects to enhance stakeholder engagement and consultation.
  • Incorporating practical and achievable sustainability related targets in tenders and performance frameworks for the management of projects and assets.
  • Benchmarking current social licence and establish pathways to enhanced social licence, consequently reducing project/asset/business risks and costs.
  • Identifying, enabling and incorporating sustainability into supply chains.
  • Reducing project or asset regulatory burden in the context of sustainability related issues.
  • Reducing environmental impact and shifting to net gain.
  • Demonstrating NZ business leadership to the region to enhance NZ competitiveness, generating business opportunities.
  • Achieving (and hopefully exceeding) New Zealand’s Paris 2015 carbon pledge targets through practical and low cost project/asset carbon reduction solutions.
  • Reducing investment risk and enhancing investment returns.
  • Demonstrating social and environmental responsibility.

To realise these benefits ISCA recommends that for every NZ IS rating registration, you determine what you would like to achieve in addition to a rating, to support better business, better investment, better relationship and better environmental outcomes, using sustainability as a lever.
