The kayak was also being towed back to shore.
"Our vessel from Papakura Coastguard is under way and making investigations but we are confident that there is nobody outstanding."
Caukwell said the lost kayak was a timely reminder for anyone who owns anything that floats on water to put their name on it, so it could be returned.
"There's no name, no identification on it and this is something that we run into a lot. If there was a message it would be to put some sort of identification on floatable water equipment, including a name or phone number - just some way to identify it because it does leave the emergency services trying to decide, are they looking for somebody or is it something that's floated away off a beach.
"If you got something that floats in the ocean can you put your name on it because it would make all our lives a lot easier."
The owner or anyone who recognises the kayak is asked to contact police on 0800 10 28 35.
