The Te Wananga O Aotearoa wellness adviser said she was supposed to be in a meeting at work.
"I said I have to go and do something for half an hour, and then bribed my boss by telling him we'd get his tickets too."
Raised in Melbourne, she has lived in Hamilton for 13 years. Ms Ohia, her partner and two sons, Mauriora, 10, and Mackisack, 8, are big Chiefs fans.
"We don't have a lot of paraphernalia but we are really huge fans in our hearts. We have come to every game this season except one."
The plan for Saturday night includes a family dinner before the rugby, and afterwards they will race home for the replay.
