Bringing the game into the city was initially aimed at getting the crowd closer to the action and more involved with the event.
With polo traditionally played in the countryside, on fields 10 acres large, the Domain provided a unique setting for spectators.
Wilson said it played a key role in the event's overall success.
"There were definitely people sitting up on the hills watching the event which is cool," he said. "Now that it's been at the Domain, people have seen where it is.
"The event that we put on is nothing without the people that come - and the amazing people that come make it very special."
Auckland's event closed a successful trifecta with last month's Urban Polo mix in Singapore and Christchurch.
