English, Māori and NZ Sign Language.
While I've only ever witnessed Māori being spoken "in the wild" twice, it's quite common to have formal addresses at public events in both English and Māori, occasionally w/ only Māori and a brief English lead in. TV news is typically in English, occasionally with a sign language translator. Given the low spread, though, I have not bothered learning Māori to date, with roughly 20,000 in close to 5,000,000 speaking it fluently the incentive is fairly small. I probably know ~ 200 Māori words and actively use maybe 30 =} (they're scattered through NZ English).
