Auckland Airport has cut its airline charges after the Commerce Commission found the airport’s forecast revenue was “excessive” and its targeted returns were unreasonably high.

In June, the commission said Auckland Airport’s revenue and targeted returns exceeded what was reasonable, but the airport’s planned investment seemed appropriate.

In its final report today, the regulator again said the airport’s forecast investment was within a reasonable range, but said its targeted returns were unreasonably high.

BARNZ Executive Director Cath O'Brien explains how this happened.
