"We've had all the people who have the skills to put an event like this together so it's been going relatively smoothly.
The temporary grandstand would be arranged in rows of the home team's colours of blue and gold which would make for stand-out visuals on live broadcast, Mr Wilson said.
"It will be quite a thing to be part of and people will get a free poncho."
Although tickets are not sold out as of yet, the main grandstand of the domain saw only a few seats left.
He said "fantastic" support from Tauranga City Council meant the event was now a reality.
This month, Mayor Stuart Crosby said that the council of the day "did a pathetic job" for fans during the 2011 Rugby World Cup, but he was confident the new council would deliver for Sunday's match.
"The aspects of it are supporting our CBD and also demonstrating that The Domain has a future," Mr Crosby said.
"I think this rugby game will demonstrate that the community would love to have rugby back at The Domain at a higher level."
Pre-game hype was expected to set the scene at the fanzone before performers led the way through the main routes to the Domain for 2.35pm kick-off.
Tauranga Samba, the Bay Twisters and Tauranga Highland Band will perform while fans enjoy the atmosphere at the dining precinct. Traffic access would be closed along the Strand to allow people a fanzone pre-game experience along the waterfront.
