One of the highlights of the Warbirds Over Wanaka airshow, which begins on Friday, is expected to be a World War I commemorative event.
A dogfight over Lake Wanaka will feature aircraft from Sir Peter Jackson's vintage collection.
Show general manager Ed Taylor said a race between six jets will be another big drawcard .
Top pilots from the United States will compete with Warbird jet pilots from New Zealand.
About 50,000 people are expected to attend the three-day event in conditions likely to be overcast but dry.
