The velodrome's capacity would need to extend beyond 1500 (involving significant engineering spending) and more permanent car parking (rather than the St Peter's School grounds) would be required.
The Government is sympathetic to such causes, and having Olympic gold medallist and chef de mission Rob Waddell in cycling's corner as a contracted commercial manager and original advocate for the velodrome means they have an ally with political clout.
Cycling New Zealand chief executive Andrew Matheson was thrilled with the event's execution.
"This needs a full debrief but the initial feedback is that it's one of the best World Cups people have attended. We've built a good blueprint and a world championships is just a longer and larger programme.
"Events like this bring a lot of money into New Zealand. We've got to demonstrate how that works so we have a clear story to tell central or local government about the true economic impact beyond just sport.
"We're a bit stretched on seat capacity but we've got an independent person assessing how the facility is affected by a World Cup load."
Matheson said public, athlete and team enjoyment of the event was paramount to its success.
"In terms of an audience, we had a mix of die-hard cyclists and a general public who were just curious. When they come in, you see their eyes light up with the phenomenal racing. It's in front of their noses, it's a gladiatorial environment and we're educating them bit by bit.
"New Zealand does big events well. We get the right mix of a precise delivery with a friendly face; teams don't feel like we're pushing or bullying them. Schedules were followed and they get good accommodation, meals, transport and a great place to race."
