Z Energy has reversed Airpoints bonuses delivered over Labour Weekend after giving customers hugely inflated sums.

In an apology letter sent to customers today, Z Energy said that instead of delivering the triple points bonus, the company had in reality credited users with much larger sums.

"Usually when you fill up at Z and swipe your Airpoints card you get 1 Airpoints Dollar for every 100 litres, or part thereof," the email says from Z Energy.

"For a Triple Airpoints Dollars promotion you should receive 3 Airpoints Dollars for every 100 litres, however, over Labour Weekend we accidentally awarded more Airpoints Dollars than were earned and we're sorry for this."

A Z Energy spokeswoman said the team made an error in the backend of the system when Airpoints Dollars were being allocated.

One customer said that he was initially credited with a $64 Airpoints bonus before having it reversed and replaced with a bonus of 64 cents.

Z Energy described the mishap as a "genuine error", and apologised for the inconvenience caused.

Z Energy customers have been able to earn Airpoints dollars since 2016, when the service station first teamed up with Air New Zealand on the programme.
