Key Takeaways

  • Positive gearing means surplus cash flow, negative gearing requires top-ups.
  • Positive cash flow often trades off with lower capital growth areas.
  • Negative gearing relies on future growth and your ability to cover losses.
  • Interest deductibility rules can change the after-tax maths.
  • Calculate all income and expenses before choosing a strategy.

Understanding gearing is essential for property investors. Whether a property is positively or negatively geared affects your cash flow, tax obligations, and overall investment strategy. With recent changes to interest deductibility rules, the gearing landscape has shifted significantly.

This guide explains what positive and negative gearing mean, how they work in practice, and the strategic considerations for property investors in the current environment.

What is Gearing?

Gearing refers to the relationship between the income a property generates and the costs of owning it. When we talk about a property being "geared," we are describing whether the rental income covers all the ownership costs or falls short.

  • Positively geared: Rental income exceeds all property expenses (including mortgage interest)
  • Negatively geared: Property expenses exceed rental income
  • Neutrally geared: Rental income exactly matches expenses

Positive Gearing Explained

A positively geared property puts money in your pocket each week or month. After paying all expenses including the mortgage, you have surplus cash.

Positive Gearing Example:

Weekly Rent: $650

Mortgage Interest (weekly): $400

Other Expenses (weekly): $150

Total Weekly Expenses: $550

Weekly Cash Flow: $650 - $550 = +$100

Advantages of Positive Gearing

The benefits of positive gearing are significant. Regular positive cash flow improves your financial position and means less financial stress if circumstances change. It becomes easier to hold the property long-term, and it may help you qualify for additional lending. Importantly, you are not reliant on tax benefits to make the investment work.

Disadvantages of Positive Gearing

The main downsides are that surplus rental income is taxable at your marginal rate, positively geared properties are often found in lower-growth areas, and they may require a larger deposit or lower purchase price.

Negative Gearing Explained

A negatively geared property costs you money each week or month. The rental income does not cover all the expenses, so you need to top up from your other income.

Negative Gearing Example:

Weekly Rent: $600

Mortgage Interest (weekly): $550

Other Expenses (weekly): $150

Total Weekly Expenses: $700

Weekly Cash Flow: $600 - $700 = -$100

Advantages of Negative Gearing

Negative gearing may allow you to access higher-growth properties in premium locations with potential for stronger capital appreciation. With interest fully deductible from April 2025, rental losses can be offset against profits from other rental properties or carried forward to offset future rental income.

Disadvantages of Negative Gearing

The risks are that it requires regular cash contributions from your income, creates greater financial risk if circumstances change, and ring-fencing rules mean losses can only offset other rental income (not your salary). You also have a reliance on capital growth to generate returns.

Interest Deductibility and Tax Treatment

From 1 April 2025, mortgage interest is 100% deductible for all residential investment properties. This marks a return to full interest deductibility after several years of restrictions, making negative gearing a fully viable strategy once again.

Current Interest Deductibility Rules (from 1 April 2025):

  • All residential investment properties: Mortgage interest is 100% deductible
  • Ring-fencing still applies: Rental losses can only be offset against rental income from other properties, not against salary or other income

While interest is now fully deductible, the ring-fencing rules remain in place. This means if your rental property makes a loss, you cannot use that loss to reduce tax on your salary or other income. However, you can carry the loss forward to offset future rental profits, or offset it against profits from other rental properties you own.

How to Calculate Your Property's Gearing

To determine whether your property is positively or negatively geared, you need to calculate all income and expenses:

Income

Start with your gross rental income and subtract a vacancy allowance typically of 2-4 weeks per year.

Expenses

Your expenses include mortgage interest payments, property management fees, insurance, rates, body corporate fees if applicable, maintenance and repairs, and other property-related costs.

Which Strategy is Right for You?

The best gearing strategy depends on your personal circumstances, goals, and risk tolerance:

Consider Positive Gearing If:

Positive gearing may suit you if you want regular passive income, prefer lower financial risk, have limited spare cash to cover shortfalls, want investments that stand on their own merits, or are comfortable with regional or secondary locations.

Consider Negative Gearing If:

Negative gearing may suit you if you have strong, stable income to cover shortfalls, are focused on long-term capital growth, want to invest in high-demand locations, have a long investment horizon, or have other rental properties with profits to offset losses against.

Choosing Your Gearing Strategy

With full interest deductibility restored from April 2025, both positive and negative gearing are viable strategies. The right choice depends on your goals: negative gearing can work well if you're targeting capital growth in premium locations and have strong income to cover shortfalls, while positive gearing provides immediate cash flow and lower risk. Remember that ring-fencing means rental losses can only offset other rental income, so factor this into your calculations.

Frequently Asked Questions

What is the difference between positive and negative gearing?
Positive gearing means your rental income exceeds all property expenses including mortgage interest, generating a surplus. Negative gearing means expenses exceed income, creating a loss. With NZ's interest deductibility restrictions, the tax benefit of negative gearing has been significantly reduced.
Is negative gearing still a viable strategy in NZ?
Negative gearing has become less attractive since interest deductibility was restricted from 2021. Investors can no longer fully offset rental losses against other income for most existing properties. New builds retain full interest deductibility for 20 years, making them more suitable for a negative gearing strategy.
How do interest deductibility rules affect property investors in NZ?
Since April 2025, only 50% of mortgage interest is deductible for residential rental properties purchased before 27 March 2021. Properties purchased after that date have no interest deductibility unless they are new builds, which retain 100% deductibility for 20 years from the code compliance certificate date.
