Waikato Regional Transport Model (WRTM)

What is WRTM?

The Waikato Regional Transportation Model (WRTM) is a multi-modal strategic model that has been used across the Waikato since 2007.  

The purpose of the model is to enable integrated planning of land use and transport, for proposals to be analysed, and possible changes in policies to be evaluated.

Specifically the WRTM assists with

  • Forecasting future traffic volumes for investment and maintenance;
  • Alternative land use policy analysis and spatial planning;
  • Testing the merits of alternative transport networks (including road and public transport);
  • Calculation of future benefits for economic evaluation of transport projects; and
  • Providing inputs into other tools to undertake more detailed intersection or urban modelling analyses.

WRTM stats 2013 to 2018

WRTM ownership

The WRTM is a jointly owned model and is currently managed by Co-Lab. 

The ownership structure of the WRTM is unique to the Waikato Region and the original ownership and shareholding has remained throughout various Governments and Governmental Department changes. 

This long-standing agreement along with strong collaboration among the shareholding parties throughout has made the WRTM an enduring success. 

WRTM Upgrade Programme

2018 Census Update

  • The 2013 version of the WRTM has been updated utilising 2018 census information and the WISE projections for the Waikato (
  • Status – 2018 Base model complete


Hamilton Transportation Model to meet the following objectives

  • Provide greater confidence informing transport and land use decisions in the Hamilton Metropolitan area  
  • Quickly and easily respond to questions and queries  
  • Test different travel choice/behavioural responses  
  • Test policy and plan changes, provide robust evidence for hearings and aid better decision making for future funding strategies/plans and business cases
  • Test the emissions impact of land use and transport interventions
  • Be ‘tightly coupled’ with both the WRTM regional model and with future microsimulation models in the Hamilton Metropolitan area 
  • Have the functionality to enable future testing of the impacts of other transport interventions 


Future scenarios

    • The process of creating future model scenarios is underway and is expected to be completed in mid-2022
    • Status – Future scenarios for 2035, 2045, 2055 are under development
    • In the interim, short term updates to the WRTM are being carried out to fix known issues.

What area does the WRTM cover?

The geographic coverage of the WRTM includes the Waikato Regional Council area from the Auckland boundary in the north, up to and including the Taupo District in the south, and from the west coast of the Waikato to the east, including the Western BOP, Rotorua District and Tauranga City.

These areas outside of the Waikato region are important in considering inter-regional journeys.
