A recent spate of recreational boating deaths is the worst Maritime New Zealand says it has seen in years.
Seven people have died in three separate incidents involving recreational vessels in the past seven weeks.
Maritime New Zealand principal advisor of recreational craft Matt Wood said the number of recreational incidents they had responded to was seven percent higher than this time last year.
Wood said it had been a busy winter for Coastguard and its volunteers had responded to more than 270 incidents and rescued 14 people from life-threatening situations.
"Thanks to Coastguard Riverton volunteers, two people were able to be saved after the fatal capsizing in Southland. While five were pulled from Manukau Harbour on Saturday, 3 August thanks to a coordinated effort involving Police Eagle, volunteers from Coastguard Titirangi and Papakura, and Auckland Airport's hovercraft."
Wood said recent incidents had been across the country, in varying conditions, and involving different sized vessels.
"This shows tragedy can occur anywhere, and it doesn't discriminate."
While boating had its risks all year round, Wood said these risks are amplified during the winter. He said it was vital to check and understand the marine weather forecast before heading out on the water.
He said boaties needed to ensure they are prepared for what can go wrong.
"We don't want any more families to have to mourn loved ones.
"We're asking all boaties to ensure their vessel, their safety equipment, and their knowledge is appropriate for the trip they want to take.
"And when in doubt, don't go out."
