The number of visitors annoyed by the continual thud of aircraft flying over Fox and Franz Josef glaciers has increased to almost one in four.
The Department of Conservation undertook two surveys over summer, and both generally show high visitor satisfaction in the glacier valleys. The surveys were done after DOC allowed more flights over Franz Josef Glacier after the collapse of an ice cave wiped out foot access.
The first survey showed that visitors to the Franz valley were mostly overseas, first-time visitors who were satisfied or very satisfied with their visit and did not mind the 5.2km return walking distance to the glacier viewpoint.
However, people "disliked" most not being able to get closer to the glacier or touch the ice, with the weather coming a close second.
The second aircraft monitoring survey showed that, although over half (61 per cent) of all visitors to the glacier valleys felt 'neutral' in terms of how aircraft had affected their visits, 24.8 per cent of respondents reported being 'annoyed' by aircraft.
