"I would certainly consider going over there one day," he told The Western Mail. "You would be foolish not to consider it.
"To experience something different in a different part of the world is something I would certainly consider."
The 29-year-old, who has also impressed for the All Blacks at centre and now has 68 caps to his name, still has a year of his current contract with the New Zealand Rugby Union to run but he has admitted that he will soon be assessing his future options.
"I would have to start thinking about my future in the next few months or so. I haven't really thought about it in too much in depth yet. I've still got another year left in New Zealand rugby.
"Contracts run out pretty fast. I'm certainly not getting any younger and my rugby playing days are getting shorter and shorter. I will sit down with my family and plan out where we see ourselves in the next four or five years."
Muliaina currently plays his rugby with the Chiefs in the Super 14 but his experiences during last month's All Black tour of the UK and Ireland have persuaded him to have a serious think about joining the ranks of either the Guinness Premiership or the Magners League. The former Auckland Blues star has spoken to a number of former international colleagues, and all have spoken positively about their moves away from their homeland.
"I spoke to Doug Howlett when we were over in Munster recently," added Muliaina.
"I asked him how things were, what the differences were and whether it was harder than Super 14.
"I've spoken to Luke McAllister - who is at Sale - as well and he is loving it. There are different reasons why players have gone over but, from what I've heard from them, they are really enjoying it."
