The All Blacks selectors saw no reason to tamper with success in naming their squad for the next Tri-Nations rugby Test against South Africa in Johannesburg on August 21.

All 26 players named on Tuesday have taken the field for New Zealand this season, with the team unbeaten and boasting a 3-0 Tri-Nations series start.

The four players added to the 22-man squad who retained the Bledisloe Cup by beating Australia 20-10 in Christchurch last Saturday were fullback Israel Dagg, prop John Afoa, lock Anthony Boric and outside back Rene Ranger.

Southland halfback Jimmy Cowan, who missed the Test against Australia due to a rib injury, has been bracketed with Alby Mathewson, who debuted off the reserves bench in Christchurch, pending the outcome of a fitness test on Thursday.

The All Blacks selectors opted for training squad members loose forward Liam Messam and midfield back Richard Kahui to remain in New Zealand.

Kahui has been sidelined in recent weeks due to a shoulder injury.
