Ben Smith not concerned about All Blacks future after sabbatical

Ben Smith has no qualms about surrendering his hold on the All Blacks No 15 jersey as he takes a total break from all rugby until the 2018 Super Rugby season.

The 31-year-old will utilise a sabbatical clause in his contract after New Zealand's second Rugby Championship clash with Australia in his hometown of Dunedin on August 26, live on Sky Sports.

"I'm not going to play any rugby at all," Smith told reporters in Christchurch, where the All Blacks have been holding a two-day training camp ahead of their opener against the Wallabies in Sydney on August 19.

"It's a real chance to take a bit of a break from footy and get my body right. It gives me an opportunity to do some other things that I think will help me."

Smith said he would take his family on holiday to Australia and the United States during his break.

He had originally planned to take the sabbatical after his Super Rugby commitments with the Highlanders ended this year but concussion issues restricted his playing time and he decided to delay the beginning of the break.

The injuries to All Blacks coach Steve Hansen's first-choice full-back forced him to tinker with his backline during the series against the British and Irish Lions.

Israel Dagg played the second Test in his preferred position at full-back before rookie Jordie Barrett got his first start in the jersey in the third.

Damian McKenzie also impressed for the Chiefs in his second successive year in Super Rugby, but Hansen named him as a fly-half for the training camp and has said the 22-year-old's future is likely to be closer to the scrum.

Smith, however, said he was not concerned at giving some of the young contenders an opportunity to usurp him in Hansen's planning ahead of the 2019 Rugby World Cup in Japan.

"There's always going to be opportunities but if I'm good enough I'll get back, and if I'm not... that's the beauty of the All Blacks. The best players play," Smith said.

"I've just got to back myself that with that time I want to be really humming coming into next year. I felt that was the best way to really push for the next couple of years."

Hansen will name the New Zealand squad for the Rugby Championship on Monday.
