A byelection to replace Far North District councillor Willow-Jean Prime, who has resigned after being voted in to Parliament on the Labour list, will not be held until next year.
Voting in the postal ballot will open on January 26, 2018, and close at noon on February 17. The result will be known that evening.
Nominations for the position will open on November 24 and close at noon on December 22.
Mrs Prime, who was number 17 on the Labour list, became an MP on September 23 and resigned from the council on September 28.
Mayor John Carter, a former MP of 24 years, wished Mrs Prime well in her move to Parliament.
"She has been a wonderful servant for our people in the Far North as a councillor and has contributed significantly to the work of council since her election in 2013. I'm sure she'll continue to represent the interests of all Northlanders from Wellington and we all wish her well," he said.
On election night Mrs Prime told the Advocate her priorities as a new MP included addressing Northland's housing problems by ensuring vacant state houses were put to use, and that more social and affordable housing was built. She would lobby for better infrastructure - including roads, broadband and cellphone coverage - and work for more jobs and training opportunities for Northland youth.
The Local Electoral Act specifies that a byelection must be held within 89 days of a vacancy occurring, unless that would cause voting to fall into the Christmas-New Year period.
About 19,200 people are enrolled to vote in the Bay of Islands-Whangaroa ward. The byelection will cost about $45,000.
