"I have been active on various issues in Wairoa since the previous elections, and we need some new ideas. Many people have said to me that I would be a good mayor, so I'm putting my hand up."
Mutonhori said his campaign is dubbed "Operation Restore Hope ki Te Wairoa".
"At the heart of this campaign is a re-engagement plan of our community to have trust, faith and confidence once again in council."
He said his goal was to "bring back trust, confidence, and sense of belonging among our people."
A mayoral election has also been guaranteed in the Tararua District Council, where incumbent Tracey Collis is being challenged by North Tararua Ward council member Sharon Wards.
There is also expected to be a contest for the Napier mayoralty, with both incumbent Kirsten Wise and Taradale Ward councillor Nigel Simpson having announced they're standing, though neither nomination had been officially declared by late-afternoon Tuesday.
Hastings Mayor Sandra Hazlehurst has been nominated again but no opponent had been declared, and no nominations had been made for the Central Hawke's Bay mayoralty, although incumbent Alex Walker has said she will be standing again.
Meanwhile, Hawke's Bay local government's four new Maori constituencies were by mid-afternoon still not guaranteed any elections with two still having no candidates nine days out from the closing of nominations.
According to on-line declarations no nominations had been received for the three seats in the Hastings District Council's Takitimu Māori Ward nor the one seat in the Tararua District Council's Tamaki nui-a-Rua Māori Ward.
But there had been one nomination in each of the Hawke's Bay Regional Council's single-seat Māui ki te Raki and Māui ki te Tonga Māori constituencies,
The wards were created in reviews last year, enabling changes in time for the triennial local body elections throughout the country this year.
Of the other local bodies in the wider Hawke's Bay area, the Napier City and Central Hawke's Bay District councils will consider Maori Ward inclusion in representation reviews ahead of the 2025 Local Elections.
The Wairoa District Council implemented a three-seat Maori Ward in 2019, as a result of a referendum vote three years earlier, but no nominations had been declared by late Wednesday.
Bayden Barber, who is standing down from the Hastings District Council after two terms and is now focusing on his new role as chairman of Ngati Kahungunu Iwi Inc, said that, having helped stage a forum to encourage new Maori candidates he had expected some nominations for the new wards to have received, nearing the end of the third of four weeks in which nominations have been open.
But he's still confident there will have been enough nominations by the time the nominations close.
While nominations for the 2022 local elections close throughout the country at midday on August 12, the official declaration of eligible candidates will not be made until the following Wednesday.
