Overseas convention centres are operating with far fewer staff than the number being touted for Auckland's proposed venue.
Sky City's convention centre will have a capacity of 3500 people.
The Government's promising 800 full-time, part-time and casual jobs.
But annual report figures show Sydney's convention centre has the same capacity, and managed with 200 full-time equivalent staff.
Melbourne's convention centre holds 5000, and operates with just 133 full-time and 273 casual staff.
