2016 Evidence Base

Page updated 3 Nov 2016

On 18 February 2014, the National Infrastructure Unit published the first cross sector infrastructure evidence base. This evidence base responds to a major constraint identified in the 2011 National Infrastructure Plan regarding lack of data to assess the performance of New Zealand infrastructure. It has been compiled using publicly available information and discussions with infrastructure sectors.

We refreshed the evidence base in October 2016 and March 2015, which ensures that the most up to date information is available to support the implementation of the Thirty Year New Zealand Infrastructure Plan 2015, released in August 2015.

The full evidence base comprises:

• An overview document, including methodology and key sector messages;
• Sector specific narratives, including an assessment of the current state of infrastructure and potential future pressures on it;
• An analysis of potential future demand pressures on infrastructure, based on sector specific scenario and trend information;
• A resilience assessment;
• A ten-year capital intentions plan.

The 2016 refresh provides an updated Capital Intentions Plan. It shows estimated spending to 2025 across central government, local government and the private sector, with the aim of giving investors greater certainty of upcoming investment needs and opportunities.

The National Infrastructure Unit (NIU) welcomes feedback on this publication, including information on further data to strengthen the evidence base.

For background information on any of the components of the evidence base, please visit the relevant pages:

• performance indicators and trends/scenario analysis
• Capital Intentions Plan
