Hon GRANT ROBERTSON (Deputy Prime Minister): Many MPs will be familiar with the game that the press gallery like to play in Parliament called the "rule in, rule out" game. There's an issue of the day and you're asked whether or not you're going to rule it in or rule it out. Sometimes it's quite a difficult game to play, you might not have made your final decision on a very complex policy issue, but Christopher Luxon got asked the very easiest rule in, rule out question of all time: would he work with Brian Tamaki?
