NZ grocery prices higher than OECD average, Commerce Commission says
New Zealand's grocery prices stabilised last year, but remained higher than in many many other developed nations, according to the Commerce Commission.
The Annual Grocery Report for 2024 also highlighted "geographic inequities", where areas like Auckland enjoyed more competition, compared to less populated regions.
"In 2024, retail grocery prices appeared to have stabilised after years of significant growth, which was reflected in a slowing of the major supermarket's gross margin growth, however, grocery prices remain higher than the OECD average," grocery commissioner Pierre van Heerden said.
However, he noted recent 2025 data showed retail prices rising, highlighting the need for more work to improve competition.
The Commission said the most recent data from 2023 showed New Zealand prices were three percent higher than the OECD average, although the gap has narrowed.
It was nine percent higher in 2022, and 14 percent higher than the OECD average in 2021.
The commission said major supermarkets maintained their national market share of 82 percent, but there had been some movement within the group.
"Pak'nSave has increased its market share while Woolworths has had a continued decline in market share over the past five years," van Heerden said.
However, he highlighted geographical differences in supermarkets' dominance.
"Consumers in Auckland and other main cities have a range of options, but consumers in smaller towns and rural areas typically have minimal to no choice within their locality, with some stores in small towns functioning as a localised monopoly," van Heerden said.
The report said in Auckland major supermarkets held 71 percent of the market, compared to 88 percent in the rest of the country.
It also found 90 percent of New Zealanders were within a 10-minute drive from a major supermarket.
The top of the South Island, West Coast, Otago, Waikato and Taranaki were where the major chains held the most dominance.

No simple solution to stimulate economic growth

Minister for Auckland Simeon Brown says there isn't a simple solution to stimulating economic growth across New Zealand. It comes as the government is being urged to inject stimulus into Auckland's economy after dismal unemployment figures for the city were released this week. Auckland saw the worst unemployment rate in the country at 6.1 percent - roughly 1 percent higher than the national figure. On Thursday, Auckland Business Chamber chief executive Simon Bridges told RNZ most of the government's plans for Auckland were long term. But Brown rejected that, and said the government were doing a range of things in the short term. "This year's Budget Investment Boost was in there to help businesses directly go out there and buy new kit, new equipment, new plant - that is about expensing that equipment so that they can actually go out there and invest with confidence," he told Morning Report. "We're doing things around tourism - Louise Upston has a huge number of events attracting tourists to New Zealand with different visa changes, digital nomads, investment rules changed through immigration with Erica Stanford. "All of these are about the now and also, Fast Tack, that is not only about the long term, making it quick and easy to get consents. "The first consent is going to be an extension to the ports of Auckland which is a $200 million project ... the good news about that is that it starts before Christmas ... those types of projects would have taken six, seven, eight years without Fast Track." Brown conceded there were still significant challenges which he said were responses to a high inflationary environment and the high interest rates. "There is no one simple solution to making sure we're stimulating economic growth across New Zealand," he said. "There are multiple things that have to be done across multiple government departments. "Whether that is immigration (and) making it easier to come here on a visitor visa." Brown said while the government hadn't made countries such as China visa free, the government had made several other changes to make it easier for tourists. "One of the changes coming that's coming in I think December is about the transit visa for Chinese visitors, that's going to make a big difference," he said. "There's going to be a new flight connection between Auckland and South America with Chinese visitors being able to transit through Auckland - that's happening later this year. "A lot of the changes are happening. Those are all going stimulate demand in the Auckland economy."

Major Gas Users Group to meet with Resources Minister Shane Jones over supply
Major Gas Users Group spokesperson Len Houwers. Photo: RNZ / Robin Martin Big industrial gas users will meet with Resources Minister Shane Jones in Auckland on Friday to discuss the problems with securing an affordable supply. Fertiliser manufacturer Ballance Agri-Nutrients, which uses gas to produce urea, has revealed it might have to temporarily close its Taranaki plant as it struggles to find a supplier of the rapidly shrinking and expensive resource . Major Gas Users Group spokesperson Len Houwers said Ballance was not the only company having such problems, and he would be meeting with Jones and other businesses to talk about how the gas market was operating. Houwers believed electricity giants were partly responsible for industrial customers not being able to secure affordable gas - the generators could afford to pay more for the increasingly scarce resource, he said, with Contact Energy recently outbidding Ballance for a seven-year contract. Meanwhile, there were medium-to-large companies that were at their financial limits, he said. However, Contact Energy defending snapping up the fertiliser manufacturer's gas supply, saying the rapidly declining resource meant hard choices had to be made. The power company said its outbidding of Ballance was for the good of country, and winning the supply meant it would be able to support hundreds more businesses and ensure energy security.

Treasury briefing points finger at government spending during Covid-19 pandemic
The Treasury briefing said the Covid-19 response showed the challenges of using fiscal policy to respond to shocks and cycles. Photo: FANATIC STUDIO / SCIENCE PHOTO L The previous government spent too much during the Covid-19 pandemic, despite warnings from officials, according to a briefing released by the Treasury. The Treasury's 2025 Long Term Insights Briefing said debt had risen in recent decades, partly because responses to adverse shocks were not met by savings between those shocks. The higher debt meant less capacity to respond to future shocks, like natural hazards, weather-related risks and biosecurity risks. Treasury estimated the total cost of the pandemic was $66 billion over the 2020-26 financial years and about 20.4 percent of GDP. The IMF and OECD estimated it was among the largest Covid-19 responses globally. The agency releases a briefing every three years, with this one looking at the role of fiscal policy through shocks and business cycles. The briefing said the Covid-19 response showed the challenges of using fiscal policy to respond to shocks and cycles. Initially, Treasury recommended "strong fiscal stimulus" at the start of the pandemic, which was cited as "perhaps" causing the economy to be much stronger than expected by the end of 2020. The wage-subsidy scheme in particular was seen as making an important contribution to the strong initial recovery, limiting the increase in the unemployment rate and enabling economic activity to resume when restrictions relaxed. Treasury then moved away from recommending broad-based stimulus, preferring more targeted and moderate support. Its post-election advice to the then-Finance Minister in late 2020 highlighted "the importance of controlling ongoing spending and ensuring it was high value to meet the medium-term fiscal challenge." By August 2021, with the Delta lockdowns coming in, Treasury recommended any decisions to provide support to businesses "should take account of macroeconomic trade-offs". It recommended against any further stimulus from Budget 2022 onwards. Wage subsidies and similar schemes during lockdowns made up about 35 percent of the costs of the response. A further 18 percent came from health-system costs, like vaccination, contact tracing, and managed isolation and quarantine. The remaining "nearly half" was made up of a wide range of initiatives that Treasury said had "varied objectives". Some were aimed at directly responding to the impacts of Covid-19, others were aimed at providing fiscal stimulus or "achieving social or environmental objectives". They included "tax changes, training schemes, housing construction, shovel-ready infrastructure projects, increases to welfare benefits, the Small Business Cashflow Scheme, Jobs for Nature, additional public housing places and school lunches". Programmes within the fiscal response that were not tied to the shock were seen as having "a lagged impact on the economy and proved difficult to unwind in later years". The report suggested cyclical management was best left to monetary policy, run by an independent central bank. It also suggested governments set out clearly when fiscal policy will be used ahead of time, including pre-defining responses. Ideally, this would have cross-party agreement. An independent fiscal institution, which could scrutinise and report on the sustainability of fiscal policy, was also suggested. The previous government had considered setting up a watchdog to cost election policies, but it could not get cross-party support. National then changed its tune, with current Finance Minister Nicola Willis supporting such a measure, but New Zealand First and ACT were opposed to the idea. Willis jumped on the report's release, saying Treasury's language was "spare and polite", but its conclusions were "damning". She said the briefing showed the challenges of using "big spending measures" to respond to one-off shocks. Willis singled out the briefing's focus on the money spent on initiatives not directly tied to the Covid-19 response. "That is a very diplomatic way of saying New Zealanders are still paying the price of the previous government extending a big-spending approach, initially intended for a pandemic response," she said.
