Economic advice for the projects that shape New Zealand.

Independent economic assessments for resource consents, plan changes, and fast-track applications, for public and private sector clients across New Zealand. Also infrastructure funding, market analysis, and peer review.

Tell us about your projectSee our work

When a project needs a consent, a plan change, a fast-track approval, or a funding decision, we provide the economic evidence that decision-makers trust and rely on. Three principals with decades of experience. More than $50 billion of projects assessed.

  • 1
    Senior people, working as a teamWe work collegially, but one principal leads your project from start to finish, so they always know exactly what you need, and by when.
  • 2
    Reliable answers, quicklyOur assessments use sophisticated models that we've built and refined since 2000, enabling accurate figures to be produced quickly and reliably.
  • 3
    Accountable to the endA second principal reviews every report before it leaves the firm, so you get the benefit of two senior minds. If a hearing is needed, we will present our evidence clearly and confidently.
  • 4
    Certainty on cost and timingEvery proposal fixes the scope, the fee, and the delivery date before you commit, so there are no surprises later.

How we work

Most projects follow the same five steps. Some skip the last one.

  • BriefYou tell us about the site, the proposal, and the timeframe. We tell you what the economics needs to cover and what it does not.
  • Scope and feeA short proposal with a fixed fee and, where it helps, options.
  • AssessmentOur team does the analysis, using models we have built and tuned to New Zealand data since 2000.
  • ReportShort, plainly argued, numbers shown, written for the people who decide.
  • Hearing, if neededWe present the evidence and answer the questions ourselves. Fraser Colegrave has done so at more than 120 hearings.
