Japan Airlines has been ordered to to pay $2.275 million after admitting price fixing on its fuel and security surcharges for cargo flown to and from New Zealand.
Its penalty was imposed on Friday - in the High Court at Auckland - for breaches of the Commerce Act.
Commerce Commission officials say Japan Airlines was one of 13 carriers against which it filed proceedings in 2008, alleging the airlines colluded to impose fuel and security surcharges for cargo shipments into and out of New Zealand.
They said the price-fixing occurred over more than six years.
Commission staff say the Japanese company is the fourth airline to accept penalties, following agreements with British Airways, Cargolux International Airlines and Qantas.
Friday's penalty brings the amount obtained by the commission in settlements from those airlines to $16.375 million.
Seven other carriers, including Air New Zealand, are due to defend charges in March 2013.
Charges against two other airlines have been dropped.
