Air New Zealand is bringing domestic jets back to Hamilton, for the first time in 25 years.

Airbus A320 Jets will fly the airline's Hamilton-Christchurch route from September.

It'll add about 25,000 seats a year between the cities.

The airline's general domestic manager, Kate O'Brien, says it's one of their fastest growing regional routes.

"We've had a number of our aircraft out - we're starting to see some of those aircraft come back into the fleet, which means that we can look to grow some of our domestic routes."
