A general aviation airport at Ardmore, near Papakura. The website describes it as a flight hub with facilities and flight services. Reviewers say there is a cafe and a WWII and WWI museum on site, and that it is a good place to watch small planes and helicopters take off and land.
One visitor who stayed at the NZMCA camp there said there are two good cafes and a good view of the aircraft. Another called it an awesome airport for general aviation and mentioned plenty of places to plane spot. Its focus on small aircraft means most of the activity is light planes and helicopters.
