Prime Minister Jacinda Ardern paid tribute to four new dames - former retirement commissioner Dame Diana Crossan, former Wellington mayor Dame Kerry Prendergast, film-maker Dame Gaylene Preston and distinguished profession Dame Margaret Brimble.
Ardern also acknowledged the work of our new knights, criminal justice advocate Sir Kim Workman, Shadbolt, our longest serving mayor, business leader Sir Rob McLeod, and paediatrician Sir Ian Hassall, the first Commissioner for Children.
"It is a special day for every one of these 196 people receiving honours. I congratulate them all and offer my sincere thanks for their contribution.''
Shadbolt told the Herald he "most definitely" planned to run for a ninth term at this year's local body elections in October.
"I have been asked if this would have an impact on the elections, the knighthood, and my response was 'well it won't do me any harm'," Shadbolt said.
At this stage, Shadbolt said first-term councillor Toni Biddle has also thrown her hat in the ring for the mayoralty and a council seat.
"It can be a strategy to heighten your profile to run for the mayoralty and to run as a councillor.
