Three Transport Accident Investigation Commission staff spent yesterday interviewing witnesses to Thursday's helicopter crash near Wanaka Airport, which killed three people.
Senior communications adviser Simon Pleasants told the Otago Daily Times there were "quite a lot of witnesses to the actual accident or just before or just after the accident" and witnesses were being spoken to while events were still fresh in their minds.
The bodies of the three victims — Nick Wallis, of Wanaka, and Paul Hondelink and Scott Theobold, of Twizel — have been taken to Christchurch for autopsiess.
Pleasants said the wreckage had been removed and was being taken by truck to Wellington for analysis.

However, an interim report could be produced.
"Sometimes the commission turns up an aspect of an accident where there is a clear indication that something went wrong and they will issue an interim report."
In those cases that report can come out just in a few weeks.
"I'm not saying that that will happen in this one but that has happened."
He was not surprised there was speculation over the cause, Pleasants said.
