New Zealand businesses have spent three months deciding whether to swallow the cost of much dearer fuel or hand it to their customers, and the first clear evidence of who is doing what has now arrived. Annual inflation reached 4.1 percent in the year to the June 2026 quarter, and buried in the detail is a sign that the country’s tradespeople are moving faster than almost anyone else to charge for the extra cost of getting to a job.
Stats NZ released the Consumers Price Index on Monday 21 July. Prices rose 1.5 percent over the June quarter alone, up sharply from 0.9 percent in the March quarter, and the annual rate of 4.1 percent is the highest since the December 2023 quarter, when it sat at 4.7 percent. It is more than a full percentage point above the top of the Reserve Bank’s 1 to 3 percent target band.
Almost all of the jump came from one place. Petrol prices rose 27.5 percent over the year and other vehicle fuels, mainly diesel, were up 71 percent. Over the June quarter petrol climbed about 20 percent and diesel about 47 percent. Stats NZ prices and deflators spokesperson Nicola Growden said higher petrol prices accounted for almost a quarter of the 4.1 percent annual increase, and that petrol and diesel together made up almost two thirds of the 1.5 percent quarterly rise.
The counterfactual is striking. Had petrol and diesel prices not moved at all, annual inflation would have been 2.9 percent, comfortably inside the Reserve Bank’s target band. Strip out the fuel pumps and this is not really an inflation problem at all.
That is exactly why the next question matters more than the headline number. A one off spike in the price of crude oil washes out of the annual figures within a year and central banks are generally advised to look through it. What they cannot look through is a fuel shock that seeps into the price of everything else, because diesel is an input into nearly every good that moves on a truck and nearly every service that arrives in a van.
The building numbers are where that seepage first shows up. The cost of constructing a new house rose 1.6 percent in the June quarter, the largest quarterly increase since the December 2022 quarter, and 2.7 percent over the year. Stats NZ said the businesses it surveys reported higher costs for materials, subcontractors, fuel and labour feeding into the prices they quote for new housing. Construction contributed 6.4 percent of the total annual inflation figure.
Shaw and Partners director Andrew Kelleher, speaking to Newstalk ZB, said the pattern in the data suggests many businesses are still absorbing the extra fuel cost rather than charging for it, but that building related pricing has moved more than most, with tradies appearing to price the increased cost of travel into their quotes.
There is a straightforward reason a plumber or a sparky would move first. A tradesperson running a ute between three or four jobs a day is carrying a fuel bill that is directly and obviously attributable to the customer being visited, and most quote job by job rather than holding a printed price list. A 47 percent rise in the diesel price over a single quarter is not something a small operator on thin margins can quietly wear for long. Larger firms with annual supply contracts, set retail prices and more room in their margins can hold out longer, and for now many of them appear to be doing so.
That restraint may not last, and it is the reason the Reserve Bank will read this release closely rather than dismissing it as an oil story. Domestic inflation, the non tradeables measure that covers goods and services not exposed to international competition, ran at 3.4 percent over the year. The tradeables measure, which captures imported goods including fuel, ran at 4.9 percent. Non tradeables inflation is the one that reflects genuinely home grown pressure, and at 3.4 percent it remains above the target band on its own.
Plenty of that domestic pressure has nothing to do with the Middle East. Electricity prices rose 12 percent over the year and 4 percent in the June quarter alone. Local authority rates and payments were up 8.8 percent. Health insurance premiums rose 19.2 percent. Those are three of the least avoidable bills a household or a small business faces, and none of them will fall back when the oil price does.
The picture was not uniformly grim. Milk, cheese and eggs were 9 percent cheaper than a year earlier, audio visual equipment fell 18.4 percent and real estate services dropped 4.6 percent. Households replacing a television or buying groceries have seen genuine relief in some aisles even as the fuel bill has climbed.
The Reserve Bank lifted the Official Cash Rate to 2.50 percent in July, its first increase in three years, and bank economists broadly expect more to follow before the end of the year. The June quarter figure came in slightly above the 3.9 percent the Reserve Bank had projected, and in line with what most bank economists had picked. RNZ reported that economists expect inflation to ease back below 3 percent by early next year, provided tensions in the Middle East do not escalate again.
Which brings it back to the tradies. If the pass through stops with the building sector, the fuel spike stays a fuel spike and drops out of the annual numbers in due course. If the businesses currently absorbing the cost run out of patience over the next two quarters and start quoting higher, a temporary shock turns into an entrenched one, and the Reserve Bank will have to keep pushing the cash rate up to deal with it. Every quote written in a ute this winter is a small vote on which of those two outcomes New Zealand gets.
