New All Blacks coach Scott Robertson said Tuesday he was pressing New Zealand Rugby to change its sacrosanct rule banning overseas-based players from Test selection, saying he wanted to pick from the best available.

The governing body has refused to budge on the issue, believing selecting players enticed overseas on big-money contracts would weaken the domestic game at Super Rugby and provincial level.

As recently as last month, chief executive Mark Robinson said they were "really happy" with demands that All Blacks selection be restricted to players based in New Zealand.
