The NZ Transport Agency Waka Kotahi (NZTA) Monetised benefits and costs manual (MBCM) is the industry's standard for the economic evaluation of land transport activities in New Zealand. The MBCM sets out economic evaluation procedures and values used in calculating benefit–cost ratios, necessary for applications seeking investment where a cost–benefit appraisal is a mandatory Waka Kotahi requirement.

The MBCM replaced the Economic evaluation manual from 31 August 2020.

Version 1.7.1 of the MBCM applies to business cases that commence on or after 19 July 2024. Please note that the only changes between Version 1.7 and Version 1.7.1 of the MBCM are the worked examples for crash analysis in Appendix 8. These changes in Version 1.7.1 are to align the crash analysis worked examples with the updated Crash estimation compendium: New Zealand crash risk factors guidelines, second edition (July 2024).

The 2023 update factors are effective from 1 July 2023. 

The MBCM should be read in conjunction with:

• the 'Benefits management guidance' section of our website, which provides an introduction to the Land Transport Benefits Framework, how to use it in planning and business cases, and benefits management in the National Land Transport Programme
  Benefits management guidance
• the Land Transport Benefits Framework measures manual (previously called the Non-monetised benefits manual), the industry's standard for the quantitative and qualitative benefits of New Zealand land transport activities.
