Gisborne mayor's top picks for Jacinda Ardern and Clarke Gayford's summer wedding

Gisborne's mayor Rehette Stoltz has revealed her top picks for when and where Prime Minister Jacinda Ardern and fiancé Clarke Gayford will tie the knot.

Gayford proposed to Ardern over Easter in 2019 on a hilltop in Mahia, just 80km south of Gisborne, where Gayford grew up.

On Monday, Ardern let slip on The AM Show the couple had decided to get married in the same area, although she wouldn't give away the date until she let her guests know first.

Gisborne mayor Rehette Stoltz said on Tuesday she was delighted to hear the occasion would occur in Gisborne.

"We are wildly excited but to be honest I expected it because Gisborne is like their second home. It's still to be confirmed but we are really, really happy," she told More FM's Breakfast Club.

The wedding is set to take place next summer and there are concerns over whether it will clash with Rhythm and Vines after Ardern mentioned "accommodation is slightly limited".

Stoltz said it will likely happen after the music festival.

"You would like to get married in summer time so hopefully around early January, after Rhythm and Vines as no one would really like their wedding while there are 30,000 other people here."

She said there are plenty of different options for weddings in the area and was excited to see what type of wedding the Prime Minister picks.

"We have fabulous venues around here - farm settings, or country settings, or the Prime Minister may even go up the coast. We have three-and-a-half hours worth of fabulous coast up north. Lots of options to choose from."

Ardern has hinted the wedding may be untraditional.

She said she felt "a bit too old to have a bridal party," and may "forgo it" because she was "getting on a bit".
