New helicopters are welcome as they have multiple roles, many of which are not combat related. I see mention above of jets for Ireland,
but in order to threaten Ireland, an adversary either has to get through Europe or the UK (or both) and possible the rest of NATO. If they have managed to do that, is there much point in Ireland having a few jets? This was effectively NZ's rationale for not replacing the A4 - a foe would probably have had to get past Australia, and if they had done that, then NZ would have no chance, so they took the pragmatic view and did not get a few newer jets. At least that was how a Kiwi explained it to me.
