"Both of them [Kaino and Saili] bring an edge, a physical edge, so we want them both out there."
Kaino, who was close to his World Cup best against the Waratahs, knows what Luatua is going through. The 31-year-old burst on to the international scene in 2004 after making a name for himself with the Under-21 World Championship team.
He had an impressive skill set for a loose forward but had nowhere near the physical edge he has now and paid the price. He didn't become a regular starter for the All Blacks until 2008 and by that time had made his weakness his strength. That sort of change takes honesty, hard work and commitment, and Kaino said yesterday he believed Luatua had what it took to turn things around.
"Steven's going well, he's been training well and he's got a great attitude as far as where he is at. We've got healthy competition in the team where we push each other and bring out the best in each other."
Kaino, back after two years in Japan following the World Cup, said he had had no contact with the All Black selectors.
"I know the competition that's in front of me. I've prepared myself for any situation so I just have to play as well as I can to be considered."
One of those rivals, Luatua, will be keen to press his claims as the June test series draws closer. Midfielder Francis Saili is in doubt for tomorrow after limping from training. Jackson Willison, George Moala and/or Pita Ahki are likely replacements should Saili be ruled out.
