Development of an online tool for rapid economic evaluation of road closure scenarios

(Client: New Zealand Transport Agency)

NZTA have undertaken pilot studies applying MERIT to real recent major network outages. This includes a pilot of the SH3 Manawatu Gorge 2011-12 outage [PDF, 403 KB].

NZTA have also developed a MERIT Primer [PDF, 741 KB] that provides a digestible summary of the findings.


Impact on Central Government Productivity (NZ)

A project is currently underway examining the productivity impacts of a major disruption on New Zealand Government agencies based in Wellington.

The project includes running a simulation of an Alpine Fault earthquake event and evaluating the economic consequences using the MERIT. Alpine Fault scenario modelling will derive the information on building disruptions from the RiskScape model. RiskScape contains building asset information for the whole of Wellington, and calculates the level of building damage (i.e., using a five-state classification system) based on the nature of the hazard event, and the ‘fragility’ of assets.

Wellington Resilience Programme Business Case (PBC)

(Client: Greater Wellington Regional Council for Wellington Lifelines Group)

This is a project initiated by the Wellington Lifelines Group. It aims to help enable smart investment decisions for public value across a raft of lifeline organisations and wider sectors.

MERIT, together with the Riskscape damage and loss modelling tool, was used to evaluate the wider economic benefits different infrastructure investment options would have. This project is due for completion mid-2018.


Other Case Studies

  • Water services outage, Auckland, NZ

    This was a single-infrastructure outage case study undertaken under the ERI programme to test and refine Non-Spatial MERIT. The pilot study was developed in collaboration with Watercare and involved a hypothetical scenario of significant interruption in water service provision in Auckland.

  • Electricity transmission outage, Auckland, NZ

    This study was part of the ERI programme, using Interoperability MERIT to assess a short-term outage associated with an electricity transmission outage in the Auckland Region. (Client: Vector/Transpower)

  • Transportation disruptions following the Kaikoura earthquake, NZ

    Non-Spatial MERIT was used immediately following the event to gauge the scale and extent of the likely disruption to transport as well as to evaluate alternative road-opening options. (Client: Ministry of Transport and Ministry of Business, Innovation and Employment)

  • Alpine Fault earthquke, NZ

    This ongoing case study, applying Non-Spatial MERIT, examines the economic consequences of a magnitude 8 earthquake on the South Island’s Alpine Fault. This is the first study involving multiple infrastructure failures to be undertaken in the ERI programme. (Client: Ministry of Civil Defence and Emergency Management)

  • Fuel supply outages, NZ

    This study is currently underway and is focused on using Non-Spatial MERIT to assess the implications of scenarios of domestic and international fuel supply outages on the New Zealand economy.

  • Economics hotspot analysis, Waikato, NZ

    This analysis is aimed at identifying limiting factors in the region’s economy, that if disrupted, could have significant socio-economic flow-on effects to both the Waikato and New Zealand economies. (Client: Waikato Regional Council, Ministry of Business, Innovation and Employment)
