Police want to speak to a couple who witnessed the fatal glider crash at Omarama on Friday last week.
Yesterday, Senior Constable Bruce Dow said the man and woman had both gone into businesses in Omarama and mentioned they had seen the glider crash into Mount St Cuthbert.
The crash killed Ichiro Murai and seriously injured Lemmy Tanner.
The woman, believed to be a New Zealander, was in her mid-50s, with blonde-white hair.
She was wearing white shorts and a black T-shirt.
The man, believed to have an English accent, had grey hair and was aged in his 60s.
They were parked outside GlenCraigs in a green four-wheel-drive vehicle with a canopy.
They had been watching gliders being flown in the area and were shocked and quite disturbed when they saw one crash, Snr Const Dow said.
He urged the couple to contact police.
He was aware of no other witnesses to the crash, he said.
