The Evaluation Strategy aims to lift the amount and availability of quality evaluation, and develop a culture in New Zealand where evaluation is embedded in the development and implementation of transport-related decisions.

The Evaluation Strategy forms part of the Transport Evidence Base Strategy.

The Evaluation Strategy:

  • Establishes a common evaluation approach for the transport sector
  • Highlights the importance of generating and using evaluation findings
  • Focuses on three main types of evaluation – formative, process/implementation and outcomes/effectiveness evaluation.
  • Provides a set of actions to enhance the availability and reuse of evaluation.

The Evaluation Strategy includes five inter-related enablers to support the generation and use of transport evidence, these include:

  1. Improve access: evaluation findings are available and presented in a digestible way
  2. Improve governance: data and information is shared between agencies to reduce project cost, and improve consistency in evaluation findings by relying on a single source of truth
  3. Invest in the right activities: we are investing in the right evaluation to deliver the greatest contribution to the transport outcomes
  4. Facilitate collaboration: the transport evaluation community is engaged to share knowledge, discuss challenges, and identify solutions
  5. Develop capacity and capability: the sector has access to the right capability to identify, specify, deliver and understand evaluation

In 2018 the Ministry of Transport commissioned Schiff Consulting to conduct an evaluation of New Zealand’s graduated driver licensing system (GDLS).

The evaluation:

  1. examined the safety outcomes of the current Class 1 (driver) and Class 6 (motorcyclist) licensing systems
  2. estimated the safety-related effects of selected recent changes to the GDLS (including changes to penalties for driver licensing breaches, raising the minimum age, strengthening the practical tests, and the introduction of CBTA).

The evaluation report is available here to download [PDF, 3.8 MB]. There is also a technical report which provides more information about the methodology including analysis and findings. Due to the large file size of the technical report, please email to request a copy.
