While a number of private boats were closer to Kohukohu it was decided to send Coastguard so no one else would be put in the position of having to break Covid isolation rules.
In the meantime, however, two people on another boat spotted the man's distress.
They rescued him and dropped him off at Kohukohu wharf where a police officer was waiting to deliver a telling off for breaching Covid regulations.
Search and Rescue incident controller Ryan Cooper, of Whangārei police, said it appeared the man hadn't tied up his kayak properly when he went on board the yacht.
It was a reminder that under alert level 4 people were supposed to avoid water recreation because of the risk to emergency services who had to break isolation if a rescue was needed.
