A mineral is “critical” because a government judges it important and its supply vulnerable—not simply because it is rare or found underground. Australia and New Zealand use the category for different national priorities, so their lists should not be treated as interchangeable. Australia’s criteria explicitly include geological potential, while New Zealand’s finalized list is intended to support its economy, technology needs and secure supply chains.
What does “critical mineral” mean?
There is no single worldwide list that makes a mineral critical everywhere. Governments use the term to identify materials important to technologies, the economy or national security, then consider whether supply could be disrupted. A mineral can therefore be important to one country and not appear on another country’s list.

Geology is only one part of the picture. A deposit’s existence does not establish that it can be extracted economically, processed domestically or supplied reliably. Governments also consider where extraction and processing happen, whether supply is concentrated, and what their industries and strategic partners need.
How does Australia select its critical minerals?
Australia’s official criteria combine national importance with supply-chain risk. A mineral must be relevant to modern technologies, the economy or national security; Australia must have geological potential for it; strategic partners must demand it; and its supply chain must be vulnerable to disruption. The Australian Government updated its lists on 20 February 2024 and says it reviews them at least every three years, with the possibility of changes in response to global strategic, technological, economic and policy developments.

Australia also has a separate Strategic Materials List. It covers materials important to net zero and other strategic applications when their supply chains do not meet the vulnerability threshold for inclusion on the Critical Minerals List. The distinction is useful: strategic importance alone does not automatically make a material “critical” under Australia’s criteria.
What do Australia’s figures tell us?
Geoscience Australia reported 31 resource commodities considered critical as of 20 February 2024. “Resource commodities” is the agency’s category; the figure is not a timeless count or a measure of how much Australia produces. Geoscience Australia’s table separately reports economic demonstrated resources and production for 2024, alongside global comparisons. Those measures answer different questions: resources indicate what is economically demonstrated, while production records output.

The count alone does not show whether Australia can turn those resources into finished materials. Extraction, processing capacity, infrastructure, workforce, environmental performance and market access all affect how much value can be captured locally.

New Zealand’s finalized critical minerals list is intended to identify minerals relevant to the country’s economy and technology needs, including clean energy and international trade, and to guide secure-supply-chain action. Its purpose reflects New Zealand’s own economic and policy context; it is not an extension of Australia’s list.
Rank #3
- Mineral collection contains 20 samples
- Set also includes a magnifier, streak plate, magnet, iron nail, index (sort) cards, sorting needle, and a lab manual
- Samples are 1" to 2" in size and are individual marked with numbers for easy identification
- Sorting (index) cards use a process of elimination to assist in identification
- Samples are packaged in a plastic tray
The Ministry of Business, Innovation & Employment connects the list to the Minerals Strategy to 2040 objective of doubling mineral exports to $3 billion by 2035. That figure is an official policy goal, not a reported current export value or an independently verified forecast. The ministry has also said it will work with partners to secure minerals that New Zealand does not produce.
The available official summary establishes those objectives but does not provide a complete inventory of list entries or a comparable production table. It would therefore be misleading to infer which specific minerals New Zealand mines, processes or imports from the list’s purpose alone.

Why do supply chains make minerals critical?
Supply risk is not the same as geological scarcity. A mineral may be present in many places yet still be difficult to obtain if extraction, refining or processing is concentrated in a small number of locations, facilities or companies. The Australian Government’s Critical Minerals Strategy 2023–2030 says: “Risks of disruption to critical mineral supply chains are heightened when mineral production or processing is concentrated in particular locations, facilities or companies.”

If a disruption restricts supply, manufacturers and infrastructure projects can face difficulty obtaining the materials they need. For Australia and New Zealand, secure access may involve a mix of domestic production, processing, trade and partnerships—not just identifying deposits.

What are Australia’s plans for capturing more value?
Australia’s Critical Minerals Strategy 2023–2030 aims to build diverse, resilient and sustainable supply chains, increase domestic processing capability, support the energy transition and capture more value onshore. It also frames development in terms of jobs and economic opportunities for regional and First Nations communities.
The strategy’s six focus areas encompass:
- Strategically important projects.
- International investment and partnerships.
- First Nations engagement and benefit sharing.
- Environmental performance.
- Enabling infrastructure.
- Skilled workforce development.
These elements show why a critical-minerals policy is broader than a list of commodities: a domestic supply chain depends on projects, processing, people, infrastructure and how development affects communities and the environment.
What is the status of Australia’s Strategic Reserve?
Australia allocated $1.2 billion in its 2025–26 budget to establish a Critical Minerals Strategic Reserve. The Australian Government said the reserve was intended to become operational in the second half of 2026. That was a stated plan and budget allocation; it does not, on its own, establish that the reserve is operating. The latest stated timing here reflects government material available as of 7 October 2026.
How should readers compare the two countries?
A useful comparison separates five questions that are easy to conflate:
- What qualifies? Australia publishes explicit selection criteria combining importance, geological potential, partner demand and supply vulnerability. New Zealand’s finalized list is framed around its economy, technology needs and secure supply chains.
- What is in the ground? Geological occurrence and economically demonstrated resources are not equivalent. Australia’s resource data are reported separately by Geoscience Australia; the cited New Zealand summary does not provide a comparable inventory.
- What is produced or processed locally? A list does not establish extraction volumes or domestic processing capability. Those require production and processing data, not just a policy designation.
- Where is the supply-chain exposure? Vulnerability may arise from concentrated mining or processing, dependence on overseas supply, or disruption affecting partner markets.
- Who benefits, and on what terms? Australia’s strategy explicitly includes local value capture, First Nations engagement and benefit sharing, environmental performance, infrastructure and workforce development. New Zealand’s stated list purpose links mineral development to its export and secure-supply objectives.
The comparison is therefore about different policy choices and supply-chain roles, not a contest over which country has the longer list. Australia’s dated count and resource reporting offer a specific picture of its policy and data at that time; New Zealand’s stated objectives explain why it has a list, but do not by themselves establish a mineral-by-mineral production comparison.
