Monitoring and focus reports
The Commission produces quarterly monitoring reports, which monitor the performance of engine fuel markets in New Zealand under the Fuel Industry Act 2020.
Fuel price monitoring – Middle East conflict
The Commission is publishing regular fuel price monitoring reports in response to the conflict in the Middle East and the impact on global fuel prices.
2 April 2026: Our latest analysis (to 1 April) shows that petrol costs have stabilised but remain higher than the start of the Midde East conflict. We're seeing prices at the pump stabilise in response, with the gap between product costs and prices (excluding taxes) returning to broadly align with what we saw before the conflict.
Diesel costs continue to increase, driving increases in prices at the pump.
Quarterly monitoring reports
These reports are based on the Commission’s analysis of the information disclosures (ID) provided by fuel companies each quarter, and provide snapshots of the competitive performance of engine fuel markets in New Zealand.
The Fuel Quarterly Monitoring Reports have been available since November 2022. In that time, the Commission has built the foundation of a solid data base that continues to grow.
Older reports
Reports older than the previous calendar year.
Focus reports
In addition to the quarterly reporting, the Commission occasionally publishes focus reports that supplement the analysis of quarterly information disclosure data.
