Inland Revenue data shows an average of about 95,000 families have received the government's fuel relief payment each week since 1 April, well short of the 157,000 families the government said would benefit when it announced the scheme in March. RNZ

A total of 106,120 families have received the payment at least once since it began, according to the Inland Revenue figures obtained by RNZ. That gap between the headline 157,000 figure and the weekly recipient count has become the crux of a dispute between the broadcaster and Finance Minister Nicola Willis, who was overheard telling Prime Minister Christopher Luxon at a media conference that the story amounted to "RNZ mischief making."

The mechanism sits inside the in-work tax credit (IWTC). The base IWTC rate was $97.50 a week before the temporary top-up was applied. Beehive IWTC Fact Sheet A 24 March government press release said that from 7 April, about 143,000 working families with children would get an extra $50 a week through the IWTC boost, with eligibility expanding to a further 14,000 families receiving a lesser top-up — bringing the combined total to 157,000. RNZ Inland Revenue confirmed the increase applied from 1 April in an official website update. IRD

By Budget Day on 28 May, the government's public language had shifted. Where the March release stated flatly that 143,000 families "will get" the payment, the Budget documents described support reaching "up to" 157,000 families — a qualifier that did not feature in the original announcement. RNZ

A spokesperson for Willis told RNZ that 157,000 families would benefit "if it remains in place for a full 12 months," pointing to the design of the scheme as the explanation for the discrepancy rather than any shortfall in uptake. The relief was structured in March as weekly support running for up to a year, or until 91 octane petrol fell below $3 a litre for four consecutive weeks — whichever came first. RNZ

Part of the gap is a function of how the IWTC itself operates rather than a failure of eligible families to claim. Households can elect to receive the credit weekly, fortnightly, or as a lump sum at the end of the tax year on 31 March. Inland Revenue had anticipated that around 20 percent of eligible families — roughly 30,000 — would opt for the lump-sum route rather than weekly payments, which by design would depress any given week's recipient count relative to the total eligible population. RNZ

That still leaves an unreconciled distance between the 95,000 weekly average, the 106,120 who have claimed at least once, and the 157,000 baseline used in both the March release and the Budget document. Even allowing for the full 30,000 lump-sum cohort, the numbers do not appear to add up to the original projection, which is the substance of what RNZ's story put to the government.

The framing shift between March and Budget Day is where the political dispute really sits. Government communications that move from an unqualified "will get" to a hedged "up to" over the space of two months invite scrutiny regardless of the underlying administrative explanation, and Willis's off-mic remark to Luxon suggests the minister's office regarded the coverage as adversarial rather than as legitimate follow-up on a public spending commitment.

The Budget 2026 Summary of Initiatives frames the fuel relief funding as time-limited, intended only to address immediate fuel-price-related pressures rather than as a permanent change to the IWTC settings. Budget 2026 Summary of Initiatives That framing matters for how the uptake numbers should be read: if the policy is explicitly temporary and contingent on petrol prices, a lower-than-projected weekly recipient count could reflect either soft take-up among eligible families or simply the mechanics of a credit that many recipients are choosing to bank rather than draw down in real time. Inland Revenue's own 20-percent lump-sum estimate suggests the department anticipated some of this variance from the outset, which raises the question of why the 157,000 figure was presented in Beehive communications without that caveat until Budget Day.

None of the sources cited resolve whether the remaining gap — beyond the expected lump-sum cohort — reflects families who are eligible but not enrolled, administrative lag in Inland Revenue's weekly processing, or a genuine overstatement in the original 157,000 projection. That distinction will matter more as the scheme approaches its 12-month sunset clause or the petrol-price trigger, whichever arrives first, since it bears directly on whether the government's cost projections for the relief were built on a realistic uptake assumption.
