Winter Games NZ and SSNZ jointly announced yesterday the world cup event would go ahead at Cardrona Alpine Ski Resort.
New Zealand's first world cup halfpipe event was held at Cardrona last year and one had tentatively been scheduled for early September.
However, behind the scenes, cash-strapped snow sports officials and organisers had been worried the world cup might not go ahead.
The event will now be held on August 25-26 and is expected to feature many of the world's top halfpipe riders.
Winter Games NZ chief executive Arthur Klap said having the top riders in New Zealand was a tremendous boost to the games, while an agreement with FIS over world cup television rights provided a "double whammy" through increased television audiences.
Mr Klap secured a contract worth more than $500,000 with Sky TV in August last year for 55 hours of broadcasting in New Zealand of all Winter Games sports at all venues.
Prime Minister John Key's announcement yesterday of $1 million towards the Winter Games was "triply important" in ensuring the success of both events, he said.
Cardrona's world cup halfpipe snowboard competition provides one of the last chances for athletes to qualify for the Vancouver Winter Olympics next year.
Cardrona has built the southern hemisphere's only Olympic-sized, 6.7m (22ft) halfpipe.
Snow Sports NZ chief executive Ross Palmer said yesterday the event was likely to be one of the highlights of the Winter Games, being held in Wanaka, Queenstown, Naseby and Dunedin in August.
New Zealand head halfpipe coach Tom Wilmott said the increased stature of the competition would give Olympic hopefuls a chance to shine and test their build-up to the Olympics.
Five athletes have already qualified for the Olympics and are required to maintain their world cup rankings. They are Juliane Bray, Rebecca Sinclair (both Wanaka), Kendall Brown (Mt Maunganui), James Hamilton (Auckland) and Ben Stewart (Whangamata).
Paula Mitchell and Mitch Brown were among other contenders for the New Zealand team.
