Wings Over Wairarapa organisers say they are gutted to announce that today's air festival and night shows will be cancelled due to bad weather.
"We are gutted to announce the news," the organisers said.
"Sunday's forecast is for showers of rain, and the chance of thunderstorms and small hail.
"Persistent rain...has created unsafe ground conditions."
The outlook is also not looking good for the Black Caps who are set to open their ODI series against South Africa this afternoon in Hamilton.
MetService meteorologist Tom Adams said occasional heavy and sometimes thundery showers were forecasted for Hamilton this afternoon and evening.
