Tom Cruise's film crew is being accused of breaking aviation rules while filming a helicopter chase for Mission: Impossible 6 near Queenstown.
QT Photo Tours owner Blair Pattinson witnessed manoeuvres by three helicopters over and under the Skippers Canyon Bridge for about 40 minutes on July 8.
He complained to the Civil Aviation Authority, Queenstown's council and the Department of Conservation two days later.
Pattinson - a freelance snapper for Mountain Scene - reckons the stunt flying might have breached CAA regulations and he thinks health and safety plans were lacking.
"For me to operate on DoC land I have to comply with health and safety guidelines.
"It doesn't matter if it is a one-man operator or a massive movie production - the public shouldn't be put at risk.
"These guys didn't seem to do that in this instance ... for this particular scene I feel it was lacking."
City Hall granted DWTT Productions - a subsidiary of US movie giant Viacom - a resource consent.
DWTT boss Peter Garner, an Aucklander, couldn't be contacted by Mountain Scene yesterday.
DoC also granted DWTT a permit to film on public land.
Pattinson was with two clients when he stumbled across the shoot for the Hollywood block-buster, involving five helicopters.
A member of the production crew, dropped off by helicopter, told them they couldn't be there as they were "in the way of filming", he says.
The production crew member told Pattinson to park on the other side of the bridge and stop vehicles trying to cross.
Helicopters flew under and over the Skippers bridge in different sequences, to the rat-tat-tat of fake gun-fire. Pattinson was surprised no traffic management was in place.
"I can only assume they were highly-trained helicopter pilots but still, risk mitigation was not there.
"I am no expert but I can imagine a traffic management plan would need to be in place to block the bridge off to traffic and members of the public to ensure their safety."
