I had written an earlier response but accidentally deleted it before posting. There were a couple of points I wanted to make.
Cyber attacks: these can be over before we even know that an attack has taken place. It may not be clear what has happened and who is responsible. Conventional military aggression- we/our our allies would likely see it coming and it would be clear what had taken place. I would imagine any first move would be in the cyber realm. FYI this as well

APKWS are a good start, but they may not be heavy enough or have the range for all jobs. I doubt NZ forces are likely to face any soviet tank armies, buy Brimstone has been the weapon of choice in A'stan, Lybia,Iraq for taking out technicals, protected firing positions etc. definitely effective, maybe not cost effective.
Lack of experience with UAVs is hardly an excuse not to move forward. The latest Def Tech Review discusses an ASPI article about the lack of UAVs on Australias LHD as a "glaring gap in capability." I have long felt the same applies to our JATF. I'm not talking of having a Triton overhead. More a ship/land deployed tactical ISR capability. Sure these may be vulnerable in a contested environment, but how contested are we talking. If it was truely contested, we would be there (at least until the yanks and Australia had done their bit). And a UAV wouldn't be any more vulnerable than a AW109 (with people on board).
Cheers.[
