Analysis by Keith Rankin, 1 May 2026.
New Zealand is almost completely dependent on four things for its survival in the contemporary world. Imported wheat, rice, and refined fuel. And ships.
Wheat
New Zealand grows wheat in the South Island, most of which becomes animal feed. Reliance on New Zealand grown wheat is forestalled by a lack of milling capacity, and a lack of inter-island shipping. Eighty percent of New Zealand residents live in the North Island.
In the last week I have seen stories of South and West Australian wheatfields being plagued by mice. It’s a recurring story in Australia. I have also seen a story about a coming ‘super El Niño’ weather event. Such an event would hit the Australian wheatfields hard; drought and fires in South Australia, and too much rain in Queensland’s Darling Downs. Further, coming constraints on fertiliser supply can be expected to hit Australia hard,
In most years, 100% of New Zealand’s imported wheat – on which the North Island is totally reliant – comes from Australia. Much of that comes in processed form, given the constraints on flour milling in northern New Zealand.
What if Australia get better offers for its possibly compromised wheat crop? New Zealand may find itself in a diminished bargaining position for its usual slice of the Australian wheat pie.
New Zealand could transition to an economy based on balanced farming, with crop-farming and horticulture taking an essential and strategic place. But that would take time. It could only happen in the medium or long term.
Rice
Rice is a second staple food in New Zealand; a grain food which is entirely imported. Reliable supplies may become hard to secure in the future; though New Zealand’s traditional reliance on Australian rice means that there may still be a degree of rice-supply security.
We note however that rice is a staple of Asia, and that East and South Asian countries are likely to be among the most adversely affected by the imminent blockade-induced global economic crisis. Rice is a Giffen good, meaning that, as its price increases, Asian consumers eat more rice, not less. (Such Asian consumers can be expected to respond to a severe economic crisis by cutting back on the kinds of foods New Zealand exports, and to eat more rice instead; this is because rice will remain cheaper in Asia than long-haul imported foods, even when the rice price increases markedly.)
New Zealand should, from next week if not last week, establish a store of rice to ensure food security during a coming crisis; a crisis which seems increasingly likely. Rice, available now, may not always be available. Rice, once cooked, can be eaten directly; it does not require milling.
Ancient Romans, at times, depended on a universal bread allowance (as well as on circuses!). A society under deep strain depends on food benefits. For New Zealand in a future crisis, rice could be the best option as a dominant emergency food staple.
Fuel and Ships
While a producer of crude oil, New Zealand imports practically all the oil-based refined fuel that it consumes. 43% of New Zealand’s diminishing oil exports went to Australia for refining in 2025, down from 99% of a much larger amount of oil in 2011. Most of the rest is now refined in South Korea and Singapore.
For fuel, New Zealand is almost completely dependent on long-haul imports on fuel-consuming ships. At least this is a two-way trade with Korea and Singapore, though imports far exceed exports. So oil tankers taking New Zealand’s oil can at least be guaranteed to return with oil. But there is no guarantee that the rest of New Zealand’s scheduled oil imports will not be redirected, in response to better offers.
On the matter of fuel, it’s very distressing to see Ukraine – now a NATO proxy – doing its best to exacerbate the global fuel crisis by destroying the oil-export capacity of Russia, the one country best placed to relieve the present global crisis. When shortages of Ukrainian wheat threatened Africa’s food supply in 2022, arrangements were made between the combatants to free-up wheat exports. I see no sign of Ukraine or NATO taking the responsible option re the global fuel supply. (Even worse, King Charles – in the King’s speech – tried to incite the United States’ president to escalate the Ukraine-Russia war; a war that can never be resolved by escalation, but which can be resolved by a neutrality deal which would ensure that German troops would never again occupy places like Kharkiv.)
Finally, there’s the issue of ships. What is happening in the world’s shipbuilding industries at present? Are aging and eroding oil tankers and container ships being replaced as they normally would be in peace times? Will there be too few ships next decade to sustain re-established global supply chains; chains which, if similar to those of recent years, almost disregarded shipping as a cost?
Conclusion
For its most basic living commodities, New Zealand is almost completely dependent on long-haul shipping; or, in the case of wheat and rice from Australia, medium-haul shipping. By sea, Adelaide is a long way from Auckland. And New Zealand has minimum short-haul (ie coastal) shipping, which could serve – in a crisis – as an efficient domestic distribution mechanism.
To avoid a food security catastrophe, New Zealand needs to store more food. Food stores facilitate any transition in land use. A substitution to the production of food staples which will feed New Zealanders will take many years.
Rice is the best staple food to store, as well as being a staple much more widely consumed in the existing new New Zealand than in the previous century.
