Aotearoa's longest-serving mayor Sir Tim Shadbolt in 'state of shock' as his deputy Nobby Clark wins mayoral race

The longest-serving mayor in New Zealand Sir Tim Shadbolt is hanging up his mayoral chains after 24 years.

His current deputy mayor Nobby Clark will be stepping into the role after two years under Sir Tim.

Looking back on more than two decades at the helm of Invercargill City Council, Sir Tim said: "I'm still in a state of shock I can't believe what's happened."

Sir Tim has almost continuously been Mayor of Invercargill since the 1993 by-election, apart from losing the 1995 race.

"I've got no regrets, I've followed tradition by bowing out gracefully and I look forward to being involved as an ordinary citizen."

Sir Tim has worn many hats as well as being Mayor in his 75 years - an activist, concrete contractor and comedian.

"Being with Sir Anthony Hopkins in the world's fastest Indian was the highlight of my creative side."

Leaving his own one-of-a-kind legacy behind.

"One of politics but politics with humour."

He's passing the torch to the current deputy mayor, Clark, who is looking forward to taking up the mantle.

"I feel ecstatic I really do, It's been a hard couple two or three years with the current council so we're looking forward to it," he said.

And he knows the role well, having served under Sir Tim as his deputy for two years.

"The mayor has been a little bit absent in the last two or three years, everybody acknowledges that and it's good that they voted him out."

Locals Newshub spoke to are looking forward to the change too.

"Sounds bloody good, bit of a change, why not."

"He has proven himself as deputy mayor but ultimately time will tell," said one.

"Yes Nobby, I actually voted for Nobby," said another.

Clark wants to make a range of changes to the council, starting with a stronger opposition to Three Waters. But for today, spending time with his nearest and dearest to celebrate the win.

"I'm going out to meet family shortly and then I'm going to a local restaurant."

A small celebration for a historic win.
