New Zealand recorded a net migration loss to Australia in 2025, according to Stats NZ, the country's official statistics agency. The figure confirms that more people moved from New Zealand to Australia than arrived in the opposite direction over the measurement period, continuing one of the most closely watched migration corridors in the Asia-Pacific region.

Stats NZ publishes migration estimates based on border-crossing records, using a 12-in-12-out rule: a person counts as a migrant departure if they have spent 12 of the previous 16 months in New Zealand and then leave, with the reverse logic applied to arrivals. Under this methodology, the 2025 result shows departures to Australia exceeding arrivals from Australia, producing a net outflow.

Who the result affects

The net loss to Australia matters to several audiences. For New Zealand policymakers, sustained trans-Tasman outflows signal pressure on the domestic labour market, particularly in sectors where New Zealanders have historically relocated to Australia for higher wages — healthcare, construction, mining and hospitality among them.

For Australia, continued net inflows from New Zealand feed a long-standing migration stream. New Zealand citizens can live and work in Australia without a visa under the Trans-Tasman Travel Arrangement, a reciprocal right that dates back decades and remains the legal basis for most of this movement. No visa application, points test or employer sponsorship applies to this pathway, which is why flows between the two countries respond quickly to relative economic conditions rather than to programme settings.

What the numbers do and do not show

A net migration loss to Australia does not mean total migration from New Zealand was negative. Stats NZ measures migration with every country separately, and New Zealand can record a net loss across the Tasman while still recording net gains through immigration from other countries. The trans-Tasman figure is a bilateral balance, not the headline net migration total.

The result also reflects both sides of the ledger: departures of New Zealanders and others leaving for Australia, and arrivals of people — including returning New Zealanders and Australian citizens — coming the other way. Stats NZ's estimates are provisional when first published and are revised as border data settles, a standard feature of the agency's migration series.

Why the corridor matters

Movement between New Zealand and Australia is the largest single bilateral migration flow for New Zealand. Because the Trans-Tasman Travel Arrangement removes formal immigration barriers, the balance of flows is driven largely by labour market conditions, wage differentials and relative living costs. When Australian demand for workers strengthens, departures from New Zealand typically rise; when New Zealand's economy outperforms, the gap narrows.

The 2025 net loss will feed into debates in Wellington on retention policy, including how tax settings, public-sector pay and housing affordability affect decisions to relocate. In Canberra, the inflow is relevant to planners tracking population growth in states such as Queensland and Western Australia, which absorb a large share of New Zealand arrivals.

Where to check the figures

Stats NZ publishes detailed migration tables, including country-by-country breakdowns, provisional estimates and revision histories, through its official website. Readers assessing the 2025 trans-Tasman result should consult those releases directly, as figures cited in secondary reporting may lag the agency's latest revisions.
