Wessex 19,
You said "With this i am refering to assisting the RNZAF in the patrolable areas to the south of NZ and their huge area of the Pacific (P3-B's), "
The RNZAF P-3 capability has remained as it always has been and we remain responsible for our own back yard.
Indeed, with our current upgrade program the Kiwi P-3s will be more capable in the Surveillance role than the Australian P-3Cs.
