Summary
The Overseas Investment Act New Zealand 2005 (OIA) restricts the purchase of sensitive New Zealand assets — including most residential property — by overseas persons — since 2018, most foreign nationals have been prohibited from buying existing homes in New Zealand; the restriction applies regardless of the purchase price; the broad ban remains in force in 2026, with only narrow exceptions for certain permanent residents, Australian and Singaporean citizens, and from 6 March 2026, a new pathway for high-value investor visa holders
From 6 March 2026, a new investor visa pathway allows holders of Active Investor Plus (AIP), Investor 1 and Investor 2 resident visas to purchase one residential property valued above NZD $5 million — this is a deliberately narrow exception; only approximately 1% of New Zealand homes exceed this threshold; OIO consent is still required; the broader ban on overseas persons buying existing homes below this threshold remains fully in force
If you are an Australian or Singaporean citizen, the rules are more permissive — Australian and Singaporean citizens can purchase most residential and commercial property in New Zealand without OIA consent, as long as the land is not “sensitive” (farmland, rural land or land near water, reserves or lakes); permanent residents of New Zealand, Australia and Singapore can also buy residential property if they are “ordinarily resident” in New Zealand — meaning physically present for at least 183 days in the last 12 months
If you are a migrant, an overseas investor or an Australian planning to buy property in New Zealand, the Overseas Investment Act New Zealand is the legislation you need to understand. It determines whether you can buy at all — and whether you need government consent before you do.
What is the Overseas Investment Act?
The Overseas Investment Act 2005 (OIA) is the primary legislation governing foreign investment in New Zealand. It restricts or regulates the purchase of:
- Sensitive land — including most residential land, farmland, rural land and land near waterways, reserves, coastlines and lakes
- Significant business assets — companies or assets above certain value thresholds
- Fishing quota
The Act is administered by the Overseas Investment Office (OIO) — a unit of Land Information New Zealand (LINZ). The OIO assesses applications for consent, applies the tests set out in the Act and can approve, decline or impose conditions on any investment.
The foreign buyer ban — introduced 2018
In 2018, the New Zealand Government introduced restrictions that effectively banned most overseas persons from purchasing existing residential property. Before 2018, overseas buyers could purchase residential property in New Zealand with relatively few restrictions.
The ban was introduced amid concern about offshore capital inflating housing prices — particularly in Auckland — and pushing home ownership out of reach for New Zealanders.
The ban remains in force in 2026. Most overseas persons cannot buy existing New Zealand homes.
Who can buy property in New Zealand — a clear breakdown
New Zealand citizens
No restrictions. New Zealand citizens can buy any residential or commercial property, anywhere in New Zealand, regardless of whether they live in the country or not.
Australian and Singaporean citizens
Generally unrestricted for non-sensitive land. Under free trade agreement provisions, Australian and Singaporean citizens are treated similarly to New Zealand citizens for most property purchases.
Exception — sensitive land: Australian and Singaporean citizens still require OIO consent to buy sensitive land — which includes farmland, rural land and land adjacent to waterways, the coast, lakes or reserves. A property lawyer will identify whether a property is sensitive.
New Zealand, Australian and Singaporean permanent residents
Can buy residential property if ordinarily resident in New Zealand.
“Ordinarily resident” means:
- Holding a NZ, Australian or Singaporean permanent resident visa, and
- Being physically present in New Zealand for at least 183 days in the last 12 months
If you hold a permanent resident visa but have not been in New Zealand for 183 days in the last year, you may not qualify.
All other overseas persons — the general rule
Cannot buy existing New Zealand residential property without OIO consent — and for most overseas persons, consent will not be granted for existing residential property.
This covers most temporary visa holders — student visas, work visas, visitor visas and most skilled migrant category holders who have not yet obtained permanent residence.
What changed on 6 March 2026
The Overseas Investment (National Interest Test and Other Matters) Amendment Act came into force on 6 March 2026, creating a new targeted consent pathway.
New investor visa pathway
From 6 March 2026, holders of the following New Zealand resident visas can apply to purchase one residential property valued above NZD $5 million:
- Active Investor Plus (AIP) resident visa
- Investor 1 resident visa (a former category)
- Investor 2 resident visa (a former category)
Key conditions:
- Maximum of one residential property per eligible investor
- Property must be valued above NZD $5 million
- OIO consent still required — applications assessed under a streamlined national interest test
- The investor does not need to be “ordinarily resident” in New Zealand (the significant relaxation from the general rule)
- The property can be lived in, used as a holiday home or used to operate a business
- Farmland and other sensitive land are excluded — the pathway covers residential property only
How narrow is this? The NZD $5 million threshold is deliberately high. Government analysis confirms approximately 1% of New Zealand homes exceed this value. In practice, qualifying properties in Auckland are concentrated in premium harbour-view suburbs and high-specification new builds at the upper end of the market.
National interest test
The same amendment introduced a new national interest test that applies to significant business asset investments — a broader change affecting commercial and corporate transactions as well as the investor visa property pathway.
What is “sensitive land”?
Even for buyers who are generally permitted to buy property in New Zealand (such as Australian citizens), certain categories of land remain restricted and require OIO consent:
- Farmland: Rural land used or capable of being used for farming
- Land near water: Land adjoining or bordering rivers, streams, lakes, the coastline or the foreshore
- Land near reserves or conservation areas: Including national parks, scenic reserves and other protected areas
- Land of special cultural or heritage significance
Your property lawyer will conduct a sensitivity check before any purchase. Most standard residential properties in cities and towns are not sensitive land. Rural lifestyle blocks, coastal properties and properties adjoining reserves may be.
The Overseas Investment Office — how consent works
If you require OIO consent, the process involves:
- Application: Submit through the OIO portal with supporting documentation
- Tests applied: The OIO assesses the investment against statutory tests — including whether you are a suitable investor (character and financial standing) and, for the new investor visa pathway, the national interest test
- Decision: The OIO can approve, decline or impose conditions (such as development obligations)
- Timeframes: Standard applications can take several months; the investor visa residential pathway is expected to have a faster process
Important: Do not enter into an unconditional sale and purchase agreement before obtaining OIO consent — consent must be obtained before completing the purchase, and most agreements include an OIO consent condition.
How the OIA affects migrants buying their first home in New Zealand
If you are on a work visa or student visa
You generally cannot buy an existing New Zealand home on a temporary visa. This is one of the most common misconceptions among new migrants.
What you can do:
- Live in rented accommodation while building your path to permanent residence
- Once you hold permanent residence and become ordinarily resident (183 days), you can buy
If you are on a skilled migrant or other residence visa
Once you hold a resident visa and become ordinarily resident (183 days in New Zealand in the last 12 months), you can buy residential property — no OIO consent required for standard residential purchases.
If you are a New Zealander returning from overseas
New Zealand citizens can buy freely regardless of how long they have been outside the country.

From 6 March 2026, Active Investor Plus, Investor 1 and Investor 2 resident visa holders can purchase one residential property above NZD $5 million with OIO consent. The broad ban on overseas persons buying existing homes below this threshold remains in force.
Do Australians need OIO consent to buy property in New Zealand?
Australian citizens can generally buy non-sensitive residential and commercial property without OIO consent. They do need OIO consent for sensitive land (farmland, rural land, coastal land and land near reserves).
What is sensitive land under the OIA?
Farmland, rural land and land adjacent to waterways (rivers, lakes, coastline), reserves, conservation areas and land of special cultural significance. A property lawyer will identify this before any purchase.
Where do I find OIO consent forms?
Through the OIO portal at linz.govt.nz. Applications can be complex — consult a property lawyer experienced in overseas investment before applying.
