United States F-16 jet-fighter pilots were "reminded of New Zealand's aviation rules" after low flights over the Fox Glacier sparked safety concerns from helicopter operators.
The pilots raised the hackles of locals during their visit for the Warbirds Over Wanaka air show.
The Otago Daily Times understands they flew close to tree level as they flew towards the glacier.
The Civil Aviation Authority said yesterday it received complaints from tourism operators in the Fox Glacier and Franz Josef areas about low-flying F-16s: "We understand the Royal New Zealand Air Force reminded the pilots of New Zealand's aviation rules, after which no further incidents occurred."
Warbirds Over Wanaka general manager Ed Taylor said he had been contacted by tourism operators who "expressed concern", and he passed that on to United States Air Force personnel in Christchurch, where the jets were based for a week before the air show.
