Christchurch City Council has agreed to look into the viability of hosting the 2030 Commonwealth Games- but not everyone is on board.

Mayor Phil Mauger is keen on bringing the Games to the region, with events spread out to the wider South Island.

Councillor Andrei Moore says without a major overhaul, the cost of hosting the event is unsustainable.

"Yesterday, councillors were briefed on a potential 15.8 percent rates rise- for us to turn around today and explore a Commonwealth Games bid is just not responsible."
