The 34-year old, capped 100 times by New Zealand, became Connacht’s biggest captured when he signed for this campaign.
His contract is due to expire in May but Connacht are keen he stays and Muliaina, who captained the province for the first time in a dramatic 30-20 win away to La Rochelle on Saturday, has not ruled it out.
“There is a little bit of talk, but at the moment I just want to concentrate on finishing (the season) well.
“I’m not looking too far ahead, there is a little bit of talk about contract extension. Certainly, it has been a real eye opener. It wasn’t what I expected and I’m really enjoying it. Who knows, we’ll see what happens,” he said.
Muliaina, who has played nine games for Connacht since making his debut in November, said he is loving life in the west. “I think the guys have been really good. I’m enjoying the environment. There is some real belief in Connacht and you know, that’s what happens when you win.
“When you implement things in the game that you’ve practised all week it’s nice when it comes off. And the belief that you see in the guys, particularly the young guys you enjoy a little bit more because you know you are a part of it. I’m loving being in Galway and being around this group.”
