Dr Lance O'Sullivan has spent the lockdown advocating for Northland residents and admonishing those who are breaking the rules, but has now admitted his own lockdown breach.
In a Facebook Live video today, the former New Zealander of the Year called himself a "silly bugger".
"I did the big shout-out about the main street Kaitaia people going and buying a pie and a Coke, and was critical of that, and was critical of that and saying how people should be staying at home," he says.
During the weekend, Dr O'Sullivan says he took a kayak out to a local beach for a quick trip.
All water activities, including kayaking, are explicitly banned under the Level 4 restrictions - rules that've been in place for four weeks.
He made the admission after he says a reporter contacted him with allegations of the breach.
"I shouldn't have done that. What a silly bugger, eh?" Dr O'Sullivan says.
"I have a thing with my kids, do as I say not as I do. I'm a d**k and I won't do that again. I put this out there, I raised this issue on Facebook, it's important that I acknowledge my shortcoming on Facebook too."
In previous live videos on his public Facebook page, Dr O'Sullivan has admonished the Government's response to the Covid-19 outbreak and a perceived lack of testing.
Twenty-seven of the country's 1451 cases are in Northland.
