The Green Party has joined the calls for an independent Parliamentary Budget Office to provide impartial costings of election promises, urging National and Labour finance spokespeople to back the move ahead of the general election.
In a letter to party finance leads, Green Co‑leader Chlöe Swarbrick said voters are being left to choose between competing figures rather than informed policy debates. The Greens argue an independent office would give the public a consistent, trusted baseline for comparing party commitments and holding politicians to account.
The proposal is not new. National’s finance spokesperson Nicola Willis has previously signalled support for a separate costings office, and Labour appears broadly amenable, though not all parties have publicly committed. Over the past 48 hours, both National and Labour have publicly clashed over shortfalls in each other’s promises, underscoring the political heat around fiscal transparency.
The Greens say the votes exist in Parliament to establish a Parliamentary Budget Office before the election if cross‑party agreement can be reached.
Supporters say an independent office would standardise assumptions, improve public understanding of trade‑offs, and reduce partisan disputes over numbers. Skeptics warn about scope, resourcing, and whether an office could be truly non‑partisan in a charged pre‑election environment.
The Greens are seeking to broaden the conversation, inviting Labour and National to formal talks to design a model with long‑term, cross‑party backing. Proponents point to international examples where parliamentary budget offices have raised the quality of fiscal debate and improved accountability.
With the election looming, the debate over independent costings is likely to intensify. If parties can agree on structure and remit, a Parliamentary Budget Office could become a lasting institutional change — one designed to shift public debate from competing claims to verifiable analysis.
