"So when you think about those things, are we putting someone in there that's just going to do that or are we putting someone in there that's going to have input in the future."
The Kiwis' first choice halves pairing of Shaun Johnson and Kieran Foran are expected to be fully fit for the Kiwis campaign, after both players missed the Warriors last round defeat to Wests Tigers with knee and back injuries respectively.
Foran is back in Sydney ahead of his move to the Bulldogs next season, spending time with his two children and family while recovering after a frustrating season with the Warriors.
"(Kiwis coach) David's (Kidwell) spoken to them both over the last couple of weeks and the general consensus is they'll be raring to go," said Nikau.
"For players that have had a couple of weeks off and a good break away from the game and spent time with their families, there's nothing better than coming into a Kiwis camp with all of your mates and looking forward to having a really good campaign."
The Kiwis face Samoa in their World Cup opener at Mt Smart Stadium on October 28.
