One of the men charged over the helicopter crash on Fox Glacier that killed seven people last year says he's done nothing wrong.
The single-engine Squirrel helicopter was taking six tourists on an aerial tour of the glacier when it crashed into a crevasse, killing all on board.
The accident happened in November last year, only moments after the single engine helicopter lifted off from the ice
The Civil Aviation Authority has stopped Alpine Adventures flying, and has charged the owner.
Quality assurance manager Barry Waterland has also been charged, and told Morning Report the charges have been laid under work safety and health legislation.
Mr Waterland said he did not accept the charges, and believed he and the company had done everything correctly, and complied with all regulations.
He said he was still trying to figure out what he was supposed to have done wrong.
"I feel as though I've been singled out, I know I'm being hounded on this. They've given us nothing to say what this is about. We're asking for the summary of facts, and it's not forthcoming at this stage, so we're completely in the dark."
A spokesperson for the Civil Aviation Authority said the matter was now with the court and they would not make further comment until the matter was concluded.
