We have produced some resources to help you explain or discuss resilience with your customers. These include a brochure of basic information and case studies. 

Resilience evaluation process

The resilience evaluation process section contains all the tools you need to undertake a thorough assessment of the resilience issues on your network. It contains links to various tools and resources that will help you build a business case for investment. Individual elements of this process are also included on this page.

National resilience assessment maps

As part of our work to understand and enhance the resilience of the state highway network, we asked Opus International to assess the resilience of the state highway network at a broad national level, and develop a methodology for assessing low frequency, high impact natural hazards at a regional level.

The national level resilience assessment was initially carried out for 9 priority programme business case corridors, located throughout the country.

The National state highway resilience – 9 priority PBC corridors [PDF, 13 MB] report outlines the findings of this work. Inside the report you will find:

  • Maps showing the resilience states for the state highways, presented as availability, outage and disruption states, and highlighting key areas of vulnerability of the state highways
  • Map showing prioritisation of the state highway network
  • A brief summary outlining the results of the assessment.

This approach has been applied to the whole state highway network.

State highway corridor resilience hazard exposure guide

This guide has been developed to help assess the resilience exposure of our state highway network for low frequency, high impact natural hazards at the corridor or sub-regional level.

Resilience and strategic case insights

This note is for Waka Kotahi NZ Transprot Agency staff and consultants who are developing strategic cases where resilience is identified as a problem. It gives examples and insights using a resilience lens on the planning process and can be used by anyone developing a strategic case who is needing to incorporate resilience into their thinking.

Resilience and programme business case insights

This report summarises the key insights from our review of the programme business cases for the top 9 priority corridors. These insights are intended to provide useful guidance for those preparing future programme business cases.

Criticality report

This report outlines a framework for evaluating the 'criticality' of routes, as part of assessing and prioritising resilience risks across the network. Building on the ONRC classes, this will allow us to also recognise Lifeline utility and essential services needs. The initial framework has now been developed and we are preparing to implement a trial to 'sense check' the framework and ensure it works well in practice.

Economic impact assessment tool (MERIT)

The Economic model technical report [PDF, 1.7 MB] has been developed to provide an understanding of the MERIT tool. It allows an assessment of the wider economic impacts of a network outage. MERIT is a dynamic, multi-regional and multi-sectoral economic model that contains all of the core features of a computable general equilibrium (CGE) model. CGE models tend to be the favoured approach and are ‘state-of-the-art’ in the modelling of regional- and national-level economic impacts. Among the advantages of this type of model is:

  1. the whole-of-economy coverage
  2. the capture of indirect and induced economic consequences
  3. the ‘general equilibrium’ impacts that result from price changes in an economy
  4. the ability to describe the distribution through time of impacts across different economic sectors and regions.

We have undertaken pilot studies applying the tool to real recent major network outages.

These include our pilot of it on the SH3 Manawatu Gorge 2011-12 outage [PDF, 403 KB] and using MERIT to produce an assessment [PDF, 719 KB] of the impact of the June 2015 lower north island floods which significantly affected SH4. We have also developed a MERIT Primer [PDF, 741 KB] that provides a digestible summary of the findings.

To give an overview of MERIT we have prepared a brief video introducing the MERIT tool [MP4, 27 MB] and the process we went through to develop the overall framework.

Coastal effects assessment guideline

The Transport Agency has developed the Coastal affects assessment guideline [PDF, 3.6 MB] in response to the Agency’s focus on long-term climate change impacts, such as sea level rise, increased inundation, and various environmental effects to ensure resilience of the New Zealand highway network.

The guide describes a coastal environment risk assessment approach intended to inform the planning, design and management of state highway assets in coastal environments. It outlines key questions to be considered based around risks to the assets and their effects on changing coastal dynamics, such as sea level rise and increasing tide or storm impacts.

Rising seas

Preparing New Zealand for rising seas: Certainty and uncertainty(external link) is a report from the Parliamentary Commissioner for the Environment  that looks at the need for New Zealand to prepare for rising seas. It says that the task of planning for sea level rise is challenging on many levels. For a start, it is technically complex, and the size and timing of impacts are uncertain. Perhaps the most difficult aspect is the impact on people’s homes, which for many are not just their homes, but also their financial security.

Climate change effects on the land transport network: research report 378

This two-stage project (undertaken in 2008/2009) aims to identify and assess the impacts climate change may have on New Zealand’s land transport networks (road, rail, ports and coastal shipping), and provides recommendations, including adaptation options, to address identified information gaps and risks.
