Wellington Maritime Police and the coastguard were kept busy on Sunday afternoon, attending four separate incidents in the lower North Island.
Acting Inspector Bruce Mackay says an aluminium dinghy sank off Pencarrow Head, in Wellington Harbour, about 1pm.
The three people aboard were wearing lifejackets and were able to swim to nearby rocks, where maritime police picked them up.
Soon after, a yacht had to be towed from near Cape Palliser, on the Wairarapa Coast, after it suffered mechanical problems.
And an unmanned jetski was found floating in Wellington Harbour.
The coastguard found its rider safe and well before being called to rescue a kayaker who had capsized in the harbour and who was also uninjured.
