New Zealand's depth at first-five is giving them a big edge over their international rivals, says former All Black coach Laurie Mains.
Beauden Barrett's performance after replacing Dan Carter in the All Blacks' victory over the Springboks at Eden Park on Saturday has highlighted the extent of the production linefor the No10 jersey.
Barrett, Aaron Cruden, Tom Taylor and Colin Slade are all waiting in the wings, with Mains saying it would give the team a boost ahead of their 2015 World Cup defence.
"It's a great time for New Zealand rugby right now, especially as we're halfway to the next World Cup, having this many resources to choose from," Mains said.
"We've just got such a wealth of riches at the moment at No10, when you've got five first-fives floating around you're really lucky."
Mains said he had never seen depth like it. "Dan Carter is quality and obviously first choice when he's available. But there's a bit of a scrap with the guys behind him, and that's how it should be. That's healthy and keeps everybody on their toes."
Rugby analyst and former All Black selector Peter Thorburn had no doubts about whom he would put in at No10 with Carter out of the equation.
"Aaron Cruden has fantastic vision on attack, and his ability to find space in behind the ruck with clever kicks has impressed me.
"Cruden's defence is top class as well, he can tackle and read the attacking line just as well as Carter.
"That's not to take anything away from Barrett, he's just not had the opportunities at international level because Cruden has been so reliable."
Thorburn said the young talent coming through in the ITM Cup was giving the All Blacks a huge boost compared with Australia, who have no domestic equivalent.
