Collins, who has made 48 appearances in the back row for the All Blacks, arrived in Wales this week.

And despite his international calibre, the 28-year-old has stated he has to prove his worth to the side if he is to become a regular fixture.

"There's a very strong squad here with options everywhere," he told the Magners League official site. "It's an honour for me to be able to come here and represent the Ospreys, but I realise that I can't take anything for granted.

"The first goal I have to set myself is to put the work in during pre-season to make sure that my body is in the best condition to compete.

“Once I've done that, we have a couple of pre-season matches to show what I can do on the field before the season proper starts.

“It's not about past reputations. Fitness and form is what dictates whether someone is going to play."
