A couple have died on a mountain in New Zealand after being trapped for two nights in high winds.

Partners Japanese Hiroki Ogawa, 31, and Nicole Sutton, 29, of New Zealand, were part of a group who reached the summit of Mount Taranaki on Saturday before encountering bad weather on the descent.

Two others made it to safety after spending one night on the mountain.

The dead pair had dug themselves into the snow and been texting police until Sunday night. But poor conditions prevented rescuers from reaching the pair until early Monday morning.

Police said that Ms Sutton was still alive when rescuers reached them but soon became unresponsive.

Poor conditions forced rescuers to leave the bodies on the mountain. They plan to try to bring them down later.
