The three-year agreement will see Tourism NZ and Jetstar each contribute $1.5 million a year to a range of joint brand, promotional and tactical campaigns, consumer events, and print, online, TV and social media activities.
Tourism NZ, a government agency charged with marketing New Zealand to the world, has similar agreements with several other airlines, including Air New Zealand.
Jetstar said the deal marked the single largest push ever undertaken by the company in the New Zealand market and was the first formal marketing partnership between itself and Tourism NZ.
The company will increase New Zealand destination content on its website to support the partnership and the marketing drive will focus on encouraging holidaymakers to visit New Zealand on Jetstar's direct Auckland-Singapore services, transtasman flights and services from Japan, via Australia's Gold Coast.
Melbourne-based Jetstar was created by Qantas to counter the threat posed by another Australian low-cost airline Virgin Blue, which is 15 per cent owned by Air New Zealand.
