"All of the incidents have been mechanical and so this is sort of typical of Labour Weekend, where people have taken their boat out for the first time after it has sat around all winter and they haven't checked the batteries, had the engines serviced or replaced the fuel in the vessel."
None of the mechanical failures or rescues had been major, she said.
Ms Smith said it was a timely reminder for boaties to get their vessels checked and safety equipment ready for the summer.
"It's a great reminder for people to get their boats ready for summer, so they can enjoy boating safely.
"Get fresh fuel, get your engine serviced and make sure you've got your life jackets and all your safety gear ready for summer."
MetService meteorologist Stephen Glassey said most of the country was experiencing settled weather today.
But that would change this afternoon as showers and potential thunderstorms developed over inland parts of the North Island, he said.
"There's been lots of fine weather in the South Island and in the North Island. There's been a little bit of cloud around some places but predominantly it's been okay," Mr Glassey said.
"Overall it's been not too bad at all for the long weekend."
The main areas affected would be Bay of Plenty, Taupo and inland parts of Hawkes Bay and Gisborne, he said.
Cold weather was also on the way this week -- with a front moving onto the South Island tonight and to the North Island on Thursday.
Snow was expected to 500m in the high country of Canterbury and Otago with the front, he said.
"It's a bit of a cold snap for the South Island tomorrow and then the North island will get it later in the week. The whole country is going to get cold on Friday.
"It will bring rain to most of the country but it moves away to the east on Friday. Things will clear up for most places next weekend but it will still be quite cold during Saturday, and start to improve after that."
