Steven Luatua opens up about leaving Blues, All Blacks

The why aspect of Steven Luatua's decision to leave New Zealand rugby at the end of this season will come as no surprise to many Polynesian athletes.

Fa'alavelave, as it is known in Samoan culture, involves family and friends contributing money or gifts to major events - or simply pulling together to support those closest to you.

Many of the Pacific Islands adopt this communal tradition based on everyone chipping in.

Luatua is just one New Zealander with strong Pacific Island heritage who feels strongly about supporting his wider family. Manu Vatuvei, Jerome Kaino and Joseph Parker have also spoken publicly about embracing the concept.

It's the main driver behind the lucrative two-year deal Luatua has signed with struggling English club Bristol.

At 25, and after 15 tests for the All Blacks, Luatua appears to be putting others before himself in the quest to maximise his earnings in order to give back to his extended family which features four siblings, 11 nieces and nephews and his own young daughter.

"The way I see it is our parents sacrificed a lot coming over from whatever Island they came from. My parents came from Samoa so we could have better opportunities," Luatua told Stuff on Wednesday of his reasoning for leaving after this season with the Blues.

"Realistically you're not going to get it right the first time. I understand that. I'm a second generation immigrant here in New Zealand and I've got an opportunity to really get it right for the next generation and my nieces and nephews as well.

"My sisters made a lot of sacrifices too, so in this aspect I'm looking after them as well. They're always in the back of my mind with my decision. I'm stoked I can do that for them.

"I won't just be giving handouts. If they come to me with an opportunity or a proper plan about what they want to do in life, especially for the kids, then I'm all for that. It means I'll write a cheque.

"I'm fortunate enough that of my siblings I was the one who had the opportunity but for my sisters' kids and my kids I want them all to have opportunities so that was the big pull for me.

"It's a massive crew and I know it's a lot of responsibility. They don't expect anything from me but as I've grown older I understand it wasn't just mum and dad that sacrificed it was a family effort. "

Luatua admits he agonised over the decision to turn down the chance to push for All Blacks selection while in the prime of his career.

All Blacks coach Steve Hansen and captain Kieran Read have both expressed disappointment about losing Luatua, but he is adamant his intention to leave was communicated to New Zealand Rugby.    

"There were a lot of sleepless nights over my decision over a couple of months. I wouldn't say I'm happy but I started this so I could have security for my family.

"I'm at a place in my life where I have a chance to make a different in my family's life. If I stayed here in New Zealand I could do a lot of good things but there is no I in team. There is I in family but not in ours we all ride the same ship. If I can help them out I want to do it."

Luatua's relationship with former Blues coach Pat Lam, who takes over Bristol next season, was a major factor, and he hopes to return to Auckland at some point in the future.

"The perception of English rugby is it's a slog and grind but having him as a head coach allows me to have that flexibility. He understands I'm still pretty young so he doesn't want to beat me up too much.

"I hope to play 100 games for the Blues. If they'll have me back somewhere down the line I look forward to that happening but I'm excited about what lies ahead."
