This Saturday the 122nd and final seat for the next Parliament will be confirmed when the Port Waikato byelection is held.
The byelection was triggered by the death of ACT Party candidate Neil Christensen before last month's election.
ACT, Labour and the Greens haven't put forward a candidate for what is thought to be a safe National Party seat, held by Andrew Bayly.
But that hasn't stopped New Zealand First's Casey Costello from having a run, and gaining momentum in the race.
Candidates Bayly and Costello spoke to Ingrid Hipkiss.
