Receiving 723 votes, Raukawa was seventh out of the nine candidates.
Raukawa told the Chronicle that she has decided to stand in the Southern Ward as her whakapapa traces back to Ratana and Turakina.
"When I went for the Central Ward, I was a bit iffy on what ward I should fit in. I live in Marton, but my marae and where I will be building a home is in Turakina," Raukawa said.
"It was a bit of 'okay, we're going again' and I'll get a chance to stand where I am originally from."
O'Gorman has not yet responded to a request for comment.
The byelection voting process begins on January 26, when the council will send out voting documents to registered electors of the Southern Ward. Election day itself is February 17, and votes must be received by 5pm that day.
The successful candidate will be formally declared on February 20.
