Moli has been helped in his front-row tuition by his flatmate, Chiefs prop Ben Tameifuna. The former Blenheim boy has a long back, in the mould of former Auckland loosehead props Craig Dowd and Paul Thomson, but he can play on the other side too.
There is little comparison between that transtasman schools international last October and the two crunch outings against the Junior Boks.
"That was a massive step up with speed, intensity and physicality. Those games against South Africa were definitely the toughest I've ever played. There were some pretty big boys in there," said Moli.
"But it's good to be playing with the big boys. At the start of this campaign. I just thought I'd be on the bench, but I've learned more and more and kept reviewing my performance."
The ITM Cup might be a season too soon, but next weekend Moli will probably be turning out for his University side and setting his sights on September's national Under-19 tournament.
Moli is not going to die wondering in the third-fourth clash with Pool B winners Ireland. He said the team were down immediately after the semifinal loss, but by next morning had picked themselves off the canvas with the express aim of finishing the tournament in style.
"We're going to finish on a high note and really bring it to them."
The New Zealand team face Ireland tomorrow at Eden Park from 5.05pm.
