The entire process takes two months. The Gateway review itself takes one week, including presenting the final report to the project’s Senior Responsible Owner (SRO).
Below is a summary of key activities in the Gateway process:

Requesting a Gateway Review
The first step in the review process is for a project/programme to assess their schedule to determine when a Gateway review would be appropriate. A Gateway review should be held some weeks before key decision points, so the review findings can inform decisions.
The Senior Responsible Owner (SRO) should contact the IMAP Gateway team to arrange an Assessment Meeting at least two months before the proposed Gateway review.

Planning for a Gateway Review
To prepare for a Gateway review, programme/project representatives and members of review teams should refer to the Gateway Process Guide, found below, and the appropriate Gateway workbook, which will outline specific criteria to be assessed and programme/project documentation required.
Agency use of Gateway collateral
The documents listed below are the core guidance for Gateway reviewers. Agencies are free to use this guidance to assist in developing internal project reviews.
Please note that The Treasury holds the Gateway™ process in New Zealand, licensed from the UK IPA. Gateway is solely a Treasury product in New Zealand:
- Any agency reviews based on this material must not be called Gateway reviews
- Agency reviews do not meet the Cabinet requirement for high-risk projects and programmes to undertake Gateway reviews, as mandated in CO(19)6.
