The watchdog alleged BP charged incorrect prices at BP Connect service stations and charges under the Fair Trading Act would be filed in the Auckland District Court.
"We expect big businesses to take the time and effort to get pricing and promotions right," commission deputy chair Anne Callinan said.
"Consumers should be able to trust the information they receive when they are buying goods and services."
The commission first opened its investigation into BP in April 2025 after receiving complaints from customers.
Customers said they bought fuel at a number of BP Connect stations and scanned their Everyday Rewards card, but did not receive the discounts as advertised.
The commission said the alleged conduct related only to BP Connect service stations, which were owned and operated by BP, not BP 2 Go sites, which were independently owned and operated.
The commission said in response to the investigation, BP has made changes and investments.
"However, since our initial investigation we have uncovered a further instance where customers allegedly did not receive the price as advertised," Callinan said.
"This instance is concerning, not only because it raises questions about the effectiveness of the company's changes, but also as it was within the current period of higher fuel prices."
However, the commission noted most of the alleged conduct occurred before the current period of higher fuel prices.
In a statement, BP acknowledged the commission's intention to begin legal proceedings relating to what it called "historical pricing accuracy matters".
"We have cooperated with the commission throughout its investigation," a spokesperson said.
"Our focus remains on serving our customers with quality fuels, dependable service, and a consistent experience across our network."
