The voice of the America's Cup says returning the event to New Zealand shores will deliver more than just sailing.

Previous editions have all been held in Auckland, but Mayor Wayne Brown says the hosting decision is in the hands of Team New Zealand boss Grant Dalton.

Brown says he'd welcome it back, but has concerns over its cost.

Sailing commentator Peter Montgomery told Ryan Bridge people aren't aware of its positive flow-on effects, like creating jobs and incomes.

“More than the whole industry, more than just the tourism industry and fans coming to fill hotels rooms or whatever. There’s been a byproduct that’s come out of it that no other sport brings.”
