New Zealand's 42 Below will launch a kiwifruit flavoured vodka in August, adding to a line-up that now includes its namesake vodka and tropical Feijoa, Passion Fruit and Manuka Honey.

The new flavour will be distributed nationwide and retail for about US$28 per 750ml bottle, a spokeswoman said.

"We always knew we would concoct a kiwifruit flavour, as 'kiwi' is synonymous with New Zealand," said chief executive Geoff Ross.

"It's taken me three years of toiling, and we are all really happy with the final taste."
