Well, currently why would they?
There is no matrix they fit into, no requirement to field anything in particular.
No one reasonably suggests that the NZDF be the size of the ADF, but what they have should be of a defined standard, that would apply to both nations & mutually support/compliment each other.
Instead of individual nations being reactive to a scenario, with adhoc capabilities, wouldnt it be beneficially prudent to both parties to have more defined response planning?
Isnt that “defence planning”?
The current situation ignores the blatently obvious reaction that both parties will in all practicality respond together anyway.
AND
mods have moved this to NZ thread, but my comments are based on inertia of ADF in embracing NZDF potential.
Re NZDF, Do members here actually believe that if either Aust or NZ were involved in an incident the other would most definitely wish or feel committed to contribute to aid the other?
I believe that of the NZ (its mutual, & Australians too) population excepting the far L demographic that won't accept anything, every other rational thinking person would expect the NZG to respond accordingly.
I also believe that has already been acknowledged by the NZG, the world is now far more volatile, that a precursor such as this scenario is the most likely cause of any NZDF mobilisation.
If the NZ population, and govt have a predisposing view that they only have to defend Rotorua, then a minimalist defence allowance can be seen as appropriate.
If the NZ population and Govt understand that they are actually part of a bigger world, despite being an independent nation with a brilliant rugby team, they are intrinsically undeniably linked in every facet to Australia and the wider South Pacific in particular, then that lends itself to the rationale of realistic defence capability.
The fact that the NZG dedicate such a small budget and priority to defence is simply an extension of them being able to believe they live in a remote bubble. This is the Australian Govt & defence planners fault.
There is a plausible fog of logic in Canberra that is seemingly totally blind to the obvious fact that in any adverse event NZ will be there.
But what can they contribute?
From a starting legal viewpoint, they are a signatory to ANZUS.
Will we be condemned to watch the NZDF scramble at the last minute to gather resources, consolidate what they have for a high end conflict? Has the ADF even bothered to consider what for example a joint maritime commander may seek from a NZ contribution whilst RAN assets are deployed further north?
I accept that I'm on the outside looking in, but in the absence of parallel capability development (capability, not specifically numbers, & it doesn't have to be the same kit, just that it does a similar thing to your key ally), the observation that NZ wanders along seemingly disjointed from its key ally lends itself to the conclusion that I'm most probably correct, even if to a fair degree.
I think it's about time we acknowledged formally that we need a co-ordinated capability plan, because we will not be responding to an event alone.
At this point, I feel obligated to point out that it has been nearly a generation since the end of the Cold War and despite a common history and shared traditions prior to the start of the Cold War, and treaties signed during it, the various AusGov and NZG's have had some very different perspectives and policies, especially with respect to defence. From my perspective, this started to become apparent at least as early as the mid-1980's, before the Cold War was even over, and possibly earlier.
In fact, viewing some of the public comments on the STUFF site, it became readily apparent to me that, for better or worse, that difference in perspective and the impact upon policies had reached and sunk into the public sphere.
From my perspective, it seems as though that perspective is the result of ideology, ignorance, and shallow thinking with all three factors feeding into and magnifying the impact of each other. The end result of a generation or more of such influences is that most Kiwis do not seem to look further than the edge of the NZ EEZ, if they even look that far, when considering New Zealand's strategic environment. Relating to that, it does seem that Kiwis had gotten into the habit of thinking NZ was demonstrating it's good world citizenship by having the NZDF involved in a large number of UN deployments, which IIRC at one point either during or shortly after the Clarke gov't, over 10% of the total NZDF military personnel (active & reserve forces), ~900 personnel, were scattered across the globe on int'l deployments and for some reason, the number of different deployments which come to mind is 27. As later gov'ts came to realise neither that scale or scope of int'l involvement was sustainable. As an aside, from my POV a token Kiwi presence might have contributed to NZ's diplomatic reputation, but it would not realistically improve international order much, if at all. It would be better, and more effective to have fewer deployments which are larger in size and therefore able to actually achieve a proper outcome.
What I found most interesting about this most recent strategic policy statement that it seems as though finally, some members of gov't seem to be acknowledging that there are both current and potential threats to NZ's lines of communication which exist outside of both NZ home waters, and the EEZ. It IMO unfortunate that that recognition seems tied to NZ interests or concerns with respect to contributing to international order, but that to me is far better continuing to subscribe to the false notion of a 'benign strategic environment' when NZ is so dependent on international trade as part of the global economy.
With respect to the overall capabilities of the ADF and NZDF, the two forces should continue to work and train together to maintain familiarity and interoperability, but the forces themselves need to be maintained separately with respect to their capabilities, as the policies of the two different nations' gov'ts can, have, and will continue to be different. There have and will be times that one gov't will decide to involve itself in some matter, or participate in an int'l incident or deployment, that the other gov't will want nothing to do with. Any arrangement where one force is reliant upon the other for a capability can lead to either a gov't being drawn into something that it wants no part of, or enable a gov't to keep the other out. Either situation would involve a loss of sovereignty, and I do not have the impression that either Australia or New Zealand wishes to merge into a unified nation at this point.
