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.
9 April 2026: Our latest analysis (to 8 April) shows that diesel retail prices have continued an upwards trajectory over the course of the week, while retail prices for petrol grades have been comparatively more stable. The week ends with a fall in crude oil prices following the announcement of a ceasefire. This is reflected in a decline in refined product costs, particularly for diesel. We will be monitoring what happens with costs in the coming days and how this is reflected in retail pricing. We note that at the start of the conflict, we saw costs rise ahead of what was reflected 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.
