In NZ, It is the responsibility of the Controller to provide terrain separation whether the aircraft is on a Radar vector direct to, or own nav direct to. This will be A130 or above, approved area MSA, 'Radar terrain' map on the controllers scope, 25NM sector altitude or VORSEC chart. The controller must specify what terrain separation is in use, eg track direct to XXXXX decend 25NM chart steps to A030 Cleared VORDME approach RWYXX
