Air New Zealand has added additional capacity to its Auckland-Rarotonga route for winter sun while Bachcare says Kiwis are also flocking to the southern ski fields - making up for lost Australian bookings.
Air NZ will increase weekly flights to the Cook Islands by two to 11 from August 16 and will add another during the October school holidays.
This would add more than 11,000 seats. The announcement comes after holiday options in Australia have been hit hard by the Covid-19 outbreak in New South Wales and some cases in Queensland.
New figures from Bachcare, New Zealand's largest holiday home management firm, show last minute domestic bookings have quickly offset gaps left by Australian tourists unable to travel to this country because of travel bubble pauses.
According to the data Queenstown and Wanaka have reached 90 per cent capacity and Arrowtown is at 88 per cent - as domestic interest in skiing during the school holidays surges.
