Questions over whether the costs justify hosting the 2034 Commonwealth Games.

The New Zealand Olympic Committee has expressed interest in bidding for the event, under a new hosting model which now allows nations to host as a whole.

Last year's Games in Birmingham was backed by $1.55 billion New Zealand of public and government funding.

Games commentator Brendan Telfer told Roman Travers the costs have seriously escalated since we last hosted in 1990.

He reckons given the galloping inflation that by 2034, it'll cost us at least $2 billion.
