North however joined Premiership outfit Northampton Saints for a deal worth around £250,000 and has scored five tries so far during his debut season playing in England.
And although not ruling out a move in the distant future, North admits winning his 50th and 100th caps for Wales - he currently has 40 - are the main goals he wants to achieve first and foremost.
"If you watch Super 15 it's awesome rugby. It's a great brand to watch and I'd never rule it [playing Super 15] out," he told Wales Online. "But for now I'm happy where I am and I'll keep on going.
"I just want to keep playing and enjoying my rugby. A big milestone for me is to win my 50th cap and 100th cap for my country. I haven't really looked any further than that at the moment.
"I've got a big end of season now with the Saints and the short-term goal is getting to the finals."
