The Tasman Warning: What New Zealand’s Property Mistake Could Teach Australia
By Leigh Martinuzzi | Martinuzzi Property Group – eXp Australia
There is a lot of noise around property policy right now, especially when it comes to negative gearing, Capital Gains Tax, investors, renters and first-home buyers.
Every time these conversations come up, the same argument gets thrown around: if we make property investment less attractive, surely first-home buyers will have a better chance. On the surface, that sounds fair. But property markets are rarely that simple.
In March 2021, Jacinda Ardern’s government removed mortgage interest deductibility for residential property investors. The idea was to “level the playing field” and make it easier for first-home buyers to compete. It sounded good in theory. In practice, it created a very different result.
The Bigger Lesson From New Zealand
The New Zealand example is useful because it shows what can happen when housing policy focuses heavily on one part of the market without solving the bigger issue underneath: supply.
The intention may have been to make housing fairer, and I think most people would agree that first-home buyers do need support. Housing affordability is a real issue. Many young buyers are doing everything right and still finding it difficult to get into the market. But this is where policy gets complicated.
If you make property investment less attractive, investors do not simply sit there and absorb the extra cost. They respond. Some stop buying, some sell, some increase rent where the market allows, and some move their property into short-term accommodation.
According to Yardney’s article, New Zealand’s Inland Revenue Department warned the government that removing interest deductibility could reduce rental supply and push rents higher. The government pressed ahead anyway, and the outcome was not as clean as the policy pitch suggested.
Rents increased, rental stock tightened, investors pulled back, and first-home buyers did not automatically benefit in the way many had hoped, because lending criteria, deposits, income, serviceability and housing supply were still major barriers. That is the part Australia needs to pay attention to.
Changing investor incentives may shift behaviour, but unless we also create more housing supply, the pressure does not disappear.
Investors Are Part Of The Housing System
I think one of the biggest mistakes in the housing debate is turning it into a battle between investors and first-home buyers.
Yes, investors compete for property. Yes, first-home buyers need a fair go. Yes, affordability matters. But investors also provide a significant portion of rental housing. Private landlords are not just people buying assets. They are also providing homes for people who rent. And not every renter is trying to buy tomorrow.
So when we talk about investors, we need to look at both sides of the equation. If investors leave the market, that may reduce some buyer competition in certain areas, but it can also reduce rental supply. And if rental supply falls in a market that is already tight, tenants can end up under more pressure.
That does not mean investors should be protected at all costs. It also does not mean policy should ignore first-home buyers. It simply means housing policy has consequences, and we need to be honest about those consequences before assuming one change will fix everything.
What This Means For The Sunshine Coast
The Sunshine Coast already has strong demand and limited supply. That demand is not going away because tax policy changes.
Across areas like Palmwoods, Woombye, Buderim, Sippy Downs, Nambour, Mooloolah Valley, Montville and the broader coastal strip, the same underlying issue keeps showing up. There are not enough suitable homes for the level of demand. That applies to buyers, and it also applies to renters.
So if investor confidence weakens, or if landlords start reviewing their long-term position, we need to understand what that could mean locally.
And on the Sunshine Coast, where supply is already tight, even small shifts in rental stock can matter. If fewer long-term rentals are available, tenants may face more competition. That can mean more applications per property, stronger rental pressure, and more difficulty for local families trying to secure a home close to work, school and community.
The issue is not just whether investors win or lose. The issue is whether the overall housing system becomes healthier, more balanced and better supplied.
Advice For Buyers, Sellers, Investors And Landlords
For buyers, policy changes can create both opportunity and confusion. But if you are buying a home to live in, you can comfortably afford it, and you are prepared to hold it for at least three, six, ten years or more, then the decision becomes more about buying well.
I would still be careful about where you buy, what you pay, and whether the property suits your long-term needs. The bigger risk is buying a property you may need to sell quickly, especially if your circumstances change or the property was not right for you in the first place.
For sellers, the key word is confidence. When policy changes are announced, that does not always mean demand disappears. On the Sunshine Coast, quality properties are still likely to attract attention, especially when they are well presented, well priced and well marketed.
For investors and landlords, this is a time to review, not panic. Look at your numbers. Understand your cash flow. Consider your debt position, rental income, maintenance costs, insurance, rates and long-term goals.
It is also important to speak with your accountant or licensed financial adviser before making decisions around tax, finance or asset restructuring. This article is property market commentary only, not tax or financial advice.
The key for everyone is to avoid reacting emotionally to headlines. Local market conditions still matter, and the right decision will depend on your own position, timeframe and goals.
Final Outlook
If Australia is looking at similar policy changes, New Zealand has already shown us what can happen. The lesson is there; we do not need to repeat the mistake ourselves.
If we want a healthier housing market, we need more homes. We need better planning, faster approvals, suitable infrastructure, more diverse housing, and conditions that make construction and long-term rental supply viable.
That is why I think the most useful conversation is not “investors versus first-home buyers”. It is how do we create a market where more people can buy, more people can rent securely, and more homes are actually built.
Look at the numbers. Understand your position. Pay attention to the local market, not just national headlines. And get proper advice before making major decisions.
At Martinuzzi Property Group, we help local property owners make sense of the market with clear, honest advice based on what is actually happening on the ground.
If you own a property on the Sunshine Coast and want to understand where your home or investment sits in today’s market, we would be happy to help.
