The campaign comes on the back of Air New Zealand's promotional $1,048 return air fair offer which is available for four weeks, ending mid-May.
"Through this joint venture we are helping maximise Air New Zealand's increased capacity on the route by driving sales, while also looking to maintain visitors out of the US over the winter low season," says Gregg Anderson, General Manager Western Markets.
"The US continues to be an important market for travel to New Zealand and we have seen some encouraging signs of improvement out of the market over the last couple of months - with a 24 per cent increase in total visitor arrivals in March when compared to a year ago."
The campaign is working to drive conversion through comprehensive online advertising featured on websites such as MSN, Expedia and Trip Advisor.
Advertising on these sites directs potential travellers through to a campaign microsite on newzealand.com where they can purchase the discounted flights.
Activity will run until 12 May and will promote return fares from key cities Los Angeles, San Francisco and Honolulu though to Auckland.
