"I think the roof's been closed every time I've played there and I've played there a few times and absolutely loved it," he said.
"So if it's anywhere close to that it'll be a great venue."
The capacity of Forsyth Barr is only around 30,000 compared to the 74,500 that Millennium Stadium can house, but Smith, who has only practiced at the Dunedin venue, said the noise increase was still noticeable to an outdoor arena.

Hammett has named rookie prop Reg Goodes to start at loosehead with the giant Ben May moving to tighthead as Jeffery Toomaga-Allen drops to the bench.
Highlanders coach Jamie Joseph has something of a loose-forward injury crisis on his hands with Nick Crosswell, Doug Tietjens, John Hardie and Elliot Dixon all unavailable, while English import James Haskell is suspended.

Joseph is set to name his team tomorrow (fri) and kick-off is at 7.35pm on Saturday.
