"Couple of highlights? Hangi in the box, it was a party in the box with kumara vodka which is so unique in this part of the country," Gunn said.
"Explored ourselves on the local beach and a quick swim at the falls. Our listeners told us that we've got to try a few things here ... it's all about people, they say g'day and have a yarn and that's what's unique here."
Gunn mentioned the weather in particular, saying they flew to Whangarei in their jackets and discarded them upon their arrival.
He visited Whangarei many years ago as part of his show, the Young Entertainers, and also with his family.
He is famously known in New Zealand from shows such as The Son of a Gunn Show and What Now in the late 80s to early 90s and more recently hosted Dancing with the Stars and Wheel of Fortune.
Gunn became the co-host of the Classic Hits FM Breakfast show for Christchurch in 2009. In 2012, he moved to a nationwide networked show with Fitzgerald on the afternoon drive show "Jase and Dave".
