Air New Zealand chief revenue officer Cam Wallace says the cheap fares are in response to the COVID-19 coronavirus impacting sales.

"With deals this good, savvy Kiwis will be able to book a relaxing weekend away, catch some autumn sun, or take the kids away to explore a new part of the country," he says.

The deals will be available on the Grabaseat website or the Grabaseat app from 9am.

The cheap fares come off the back of Air New Zealand offering flights to Australia from $69, which was also done to fill empty seats left by the COVID-19 outbreak.
