"You don't want to let the boys down by not knowing your role and the calls of the plays and stuff, so I'm trying to take what I'm learning home."
The 25-year-old said he was enjoying the challenge of switching codes and couldn't wait to get a game at FMG Stadium Waikato.
"I've played there before. We had a trial game there against Penrith in 2013 and it is a fast track so I'm looking forward to getting out there again."
The speedster, who scored 15 NRL tries in 25 games, is not 100 per cent sure which position coach Dave Rennie will put him in, but would like a crack on the wing.
"I haven't really spoken to the coaches about that yet. But I'm definitely keen to give that wing spot a crack and put my hand up during this pre-season."
Fisiiahi has moved to Hamilton with his wife and said he was enjoying the relaxed lifestyle compared to Auckland.
"I drove to training one morning and it took like 10 minutes and some of the boys were like, 'were you stuck in traffic?'," he said with a laugh. "It is a lot different to Auckland and the traffic is all pretty free-flowing for me."
Fisiiahi, who played rugby at Wesley College before switching to league, said one of his favourite parts of the pre-season was watching old footage of Chiefs games.
"I think what excites me is when they show old footage of Chiefs players and old games, it's just like, far out, all these Chiefs greats used to play here, and if I slip on the jersey I want to do it for them and honour the past.
"I want to honour the present as well and myself and my family and do them proud. And that gees me up."
