Air New Zealand says it's working hard to rebuild trust in the regions.
The airline says 86% of flights arrived within 15 minutes of schedule last month, up from just over 78% a year ago.
Analytics company OAG rated the airline at just over 84% for June, including cancellations.
Ground and In-Flight Chief Operations Officer Kate Boyer told Mike Hosking customers don't care about statistics, they want their flights on time.
She says one bad flight can wipe out six or seven good ones, so they're committed to proving themselves to customers.
