Stacey Jones has yet to decide what role Phoenix Crossland might play in New Zealand's World Cup semi-final against Tonga on Saturday.
"We have got Te Maire Martin too. It is no given that Phoenix will play. Now with the six-man bench, you get more flexibility."
Crossland returns from a four-game suspension and has been named on the extended bench for the match at McDonald Jones Stadium.
He won Newcastle's Danny Buderus Medal as the club's player of the year after a strong season, including a gritty preliminary-final victory over Penrith.
Jeremy Marshall-King has impressed at hooker, but Crossland's return gives New Zealand another option.
Marshall-King started last year's Pacific Championships, which New Zealand won, but injured himself in the opening game and missed the final; Crossland took over at hooker.
"I think for myself it's just being the best I can. The hooker role is up for grabs and we challenge each other in training," Marshall-King said.
He said New Zealand's forwards made him feel safe and expected a grinding contest against Tonga's big pack.
