Thank you in advance for your answers to these 21st century questions.
1. In any battlefield in which NZ forces are engaged in combat. The L118 (current NZ gun) has been employed operationally (and very successfully) in Africa, Europe, South America and the Middle East. Other 105mm artillery types have been employed in South East Asia (including by the NZ Army). None of these environments have presented any particular issue with operating such a system there. Please note however the term: battlefield. Capabilities such as artillery are warfighting capabilities.
2. If such an invasion occurs? Yes of course they will. Force protection measures will be used to protect any asset. Camouflage, concealment, tactical positioning and re-positioning. Electronic warfare, counter-UAS systems deployed by NZ or allied forces and offensive operations by the artillery unit and other NZ and allied units. Whether these are successful or not is the same as any other hypothetical question. Here is a related question. What stops China from killing any NZ drone operator? A person is easier to kill than an artillery piece after all. What stops a Chinese drone operator being killed by a 105mm artillery strike for that matter?
3. How does NZ move any forces to these islands to engage in island warfare? NZ has air and maritime transport capabilities does she not? Her allies have air and maritime transport capabilities do they not? How do they support deployed capabilities? Why, by their transport and logistic capabilities of course… How do you imagine countries manage to keep up a supply of attritable drones or indeed any ammunition natures to their forces? Again, force protection measures. If this warfare scenario is as one sided as you paint the picture, it won’t matter which system you operate. But I get the feeling you don’t really understand how anyone would be fighting this island warfare you imagine might occur. Suffice to say it won’t be fought by digging in and waiting for overwhelming Chinese firepower to turn up and obliterate them, as you seem to imagine will happen. If they do, neither artillery nor drones will matter much.
4. They could of course, but the Western Front was a while back and forces don’t really fight this way any more. The widespread use of motor vehicles instead of horses kind of made that style of fighting redundant. Helicopters and aircraft made it even more obsolete. If NZ Army L118 guns were deploy to assist Australian forces engaged in land warfare in Australia they would be moved (in theatre) primarily by their gun tractors. Or by helicopter. Or by boat / ship. Or by fixed wing aircraft. Or by rail.Or civilian trucks. So basically all the ways we would move any forces in such a scenario.
5. I have stated as much already. You seem to be of the belief that this is an and / or situation. You are aware (I presume in these answers) that the NZ Army already concurrently operates both drones (of various types) and artillery systems? These drones are (in part) employed directly in support of NZ artillery operations, being used for FO parties (google it) and general ISR / targeting operations.

What sort of return on investment do your envisaged armed drone units provide in peacetime? What sort of return on investment do your Javelin missiles provide? They provide their return on investment in wartime when you have to engage in actual combat and if you are foolish enough to fail to invest in them in peacetime, you’ll probably have a different view of the wisdom inherent in that decision should you find yourselves in a combat situation. Tolkien argued this point better than I ever could. “Those without swords, can still die upon them.”
6. You could build a tank factory if you really wanted to. The desirability / need or financial viability of such however is what has to be assessed aka the “business case”. It might be in NZ’s interest to develop a local military drone industry, but you have purchased from other all the major drone systems your military uses, from companies and countries that already produce such. You do the same with artillery and your artillery ammunition. The quantities of such that NZ acquires usually makes local manufacture cost-prohibitive however. Feel good “made at home” and “desirability” concepts only go so far afterall and budget realities usually intrude way before these other philosophies could impact the decision however.
7. And where do these drone teams get their attrited drones from? Who resupplies them and by what means? How do you protect small unit, light infantry teams from the counter-battery fires and indeed heavier combat units they will be facing? Have you any idea whatsoever of what happens to light forces when they have to try and oppose heavy conventional forces? Particularly ones that are themselves well-supplied with the sorts of drones you seem to be so enamoured of? How do these light fires (at best) support your conventional forces? How do the light strikes these drones are capable off, achieve suppressive effects on the battlefield?
Bit of a 20th century concept I know, but you actually have infantry forces in the NZ Army. One of their jobs besides filling sandbags and conducting humanitarian assistance operations, is to train to assault the enemy in formations known as sections, platoons, companies, battalions and so on.
They can do so with support, or without it. Old-fashioned history has shown they perform much better when they aren’t slaughtered by enemy machine gun and explosive fires for every step they advance. We could go back to 1914 and try that again, but with the added addition of light drone strikes, but I am not sure you’ll be particularly happy with the results.
Some bright sparks realised that rather than have their unsupported infantry decimated by enemy fires, they could actually fire their own support weapons as their infantry was advancing, which would cause the enemy to decide between being decimated in their turn or to bunker down and not be decimated by these fires. It also had the added benefit that the enemy found it impossible to fire their own weapons unless they felt like being slaughtered. Another bright spark also realised that human bodies are not particularly bullet or fragment resistant, but steel is and if you encased a human being in steel and put wheels or tracks on this structure said human bodies could maneuver around a battlefield. Better yet, they could carry their own firepower of greater range and lethality than any human being could manage and if they too were supported by offensive fires, well you’d have yourself a combined arms system that could perform all sorts of tasks and stand a more than reasonable chance of surviving contact with an enemy.
In recent times it has become easy and quite fashionable to imagine that revolutionary airborne systems such as an FPV drone has fundamentally and irrevocably changed the status quo in land warfare. Reels show drones killing everything from people to tanks and ammunition dumps seems to dominate mil-interested social media feeds, adding to this fascination. Some even suggest this technological advance should replace traditional capabilities because of the drones ability to destroy a target. Cool. Is that all that matters? Missiles have been able to do that for 60+ years too. Has that capability rendered traditional capability obsolete? Or does context, nuance and adaptation have some role to play here? more than a few professionals have studied these matters is significant detail. Here is one of my personal favourite pieces on such topics.
You might be surprised to hear that researchers have also studied the survivability of towed artillery guns on modern battlefields and there are surprising results. One of the results of studies on Ukrainian artillery operations, is that scoot and shoot is a far less useful tactic than you might imagine and the reason is that modern loitering munitions are far better at locating and attacking moving vehicles and people, than they are static, well-concealed and well camouflaged targets, including artillery guns.
Large self-propelled vehicles whilst being easy to locate whilst moving are also concomitantly more difficult to camouflage and conceal. Modern drone survival tactics therefore are focussed on site selection and dispersal, good camouflage / concealment and cover where possible, noting that crest clearances become an issue if attempting to fire within heavily vegetated areas, even though they undoubtedly add to concealment. Other tactical means of increasing survival are also feasible and are detailed at length here:
It might even be the case that the small, humble 105mm gun becomes more effective than ever, given it’s portability, small relative size, ease of concealment and possible overall survivability compared to large “more capable” systems. The introduction of guided 105mm rounds may also contribute to keeping the calibre alive, with reduced necessity of firing of course likely to contribute to increased survivability.
NZ might be better off with newer guns, but then given the above, they might be better off improving the light guns they currently have with better munitions, fire control systems, etc. I am not an artillery expert by any means. If one of their intended jobs is to support Australian forces under Plan ANZAC or similar, well there is little arguing these 105mm guns offer at least a capability difference to the types of artillery capability Australia now maintains.
