Deconstructing the New Zealand Transport Agency Economic Evaluation Manual: Bringing the best research on transportation and its economic benefit into the applied New Zealand context

Abstract

This paper explores the New Zealand Transport Agency Economic Evaluation Manual from the perspective of best practices in international literature. Drawing upon research from the international community and policy-focused bodies like the OECD, the paper seeks to improve the NZTA EEM’s quality by employing hedonic and revealed-preference methods to create a more accurate tool to derive the value of certain transport investments. The paper finds that the value of time in New Zealand is far too low, the discount regime improperly reflects the nature of such investments, cycling benefits are undervalued, and property values are not accounted for as well as they could be. The paper then applies these findings to the recently-completed Public Transport Spine Study in Wellington, New Zealand to illustrate the importance of accurate economic evaluation of transport investments.
