All Black coach Graham Henry has said that he is not concerned about South Africa sending a depleted squad to contest the Tri-Nations in Australasia this year, explaining that he is focused on his own side's preparations.

The Springboks have announced an unusually long injury list in what is being interpreted as an attempt to rest their key players ahead of the World Cup, as they did in 2007, but Henry is considerably less hot under the collar about the decision than others in New Zealand.

He told allblacks.com: "My thoughts on that [South Africa's policy] are immaterial. My thoughts have to be on what is best for our guys. I respect what they [South Africa] have to do and that is their strategy for this particular rugby year.

"We have to have our own strategy that we put into practice and make sure we have got a lot of communication about that," he said.

The All Blacks have a bit of a unique situation on their hands as the players in the squad who are from Christchurch have had to deal with the trauma of the earthquakes this year and the extra travelling they were forced to do while playing for the Crusaders.

Henry explained that his management team will have to consider how they are going to handle the situation very carefully.

"Making sure we have got very clear communication on this and making sure we do the right thing by each individual which is also positive for the team is going to be very important," he said.

The All Blacks mentor was at pains to point out that players who did not make the Tri-Nations squad, may still have important roles to play in this World Cup year as injuries could threaten any player.

He is also looking to some seasoned All Blacks, such as Sitiveni Sivivatu and Corey Jane, to repay his faith in them after underwhelming Super Rugby campaigns.

"They have played some outstanding rugby for the All Blacks but they haven't really performed in Super Rugby this year," said Henry.
