Lower Hutt and Porirua are in a race to vaccinate their way to ninety percent first.
Data released by the Ministry of Health in October showed suburbs in both cities struggling to hit the mark.
Porirua Mayor Anita Baker will sing a "ditty for his city" if she loses, and Campbell Barry will do the high ropes at Adrenaline Forest if Porirua wins.
Baker and Barry spoke to Corin Dann.
