As the last weekend of the summer boating season approaches, Coastguard urges boaties to be prepared and check the forecast before going out.
An already storm-battered North Island is expected to receive more heavy weather during Easter weekend as Cyclone Cook - a category three storm - makes its way to New Zealand from New Caledonia.
"It's essential for everyone to take proper safety precautions before heading out on the water this weekend, including checking the weather forecast and not going out on the water if it doesn't look good," says Coastguard CEO Patrick Holmes.
"New Zealand's weather is highly unpredictable and can change in an instant. Coastguard recommends that everyone planning a day on the water should check the local marine weather forecast before they go and expect both weather and sea state changes."
Boaties are also reminded that any reports of damaged vessels or vessels that have drifted from moorings should be directed to the relevant Harbour Master for each area.
"As well as checking the forecast, Coastguard recommends that everyone on board a boat less than six metres should wear a lifejacket while underway.
