New Zealand mortgage interest rates can be a complex and ever-changing landscape. The Reserve Bank of New Zealand (RBNZ) sets the Official Cash Rate (OCR), which has a direct impact on mortgage interest rates.

In recent years, the OCR has been lowered to record lows, making borrowing cheaper for many Kiwis. This has led to an increase in mortgage applications and a rise in the housing market.

However, with low interest rates come concerns about the sustainability of the housing market. Some experts warn that low rates can lead to a housing bubble, making it difficult for people to afford homes in the long term.

If you're considering taking out a mortgage or refinancing an existing one, it's essential to understand your options and how interest rates will affect you.

Mortgage Interest Rates

Mortgage interest rates can be a complex and confusing topic, but let's break it down in simple terms.

Floating rate mortgages have a floating rate that only moves when the Reserve Bank changes the Official Cash Rate (OCR), making them more expensive but flexible.

Borrowers who want long-term certainty often opt for a three-year fixed rate, which is the most common choice among borrowers.

The bank with the lowest interest rate can change over time, making it difficult to compare rates between banks.

Here are some interest rates available from major banks in New Zealand:

It's not always about choosing the lowest interest rate, but rather where you think interest rates will go. If you think rates will rise, a shorter fixed rate might be a better choice.

Generally, more conservative property owners fix their rates for longer, while those who are comfortable with variation fix for shorter.

One strategy used by many investors is to choose the 1-year interest rate every year, which would have given you the lowest rate on average over the last 20 years.

Mortgage Types

There are several types of mortgages available in New Zealand, each with its own set of benefits and drawbacks.

A fixed-rate mortgage locks in a set interest rate for a specified period, usually 1-5 years, providing stability and predictability for homeowners.

Variable-rate mortgages, on the other hand, have interest rates that can change over time, often in response to market conditions.

A 2-year fixed-rate mortgage, for example, might offer a lower interest rate than a variable-rate mortgage, but it also comes with a higher interest rate after the fixed period ends.

Home equity loans allow homeowners to borrow against the value of their property, often at a lower interest rate than a traditional mortgage.

Three Year Term

The three-year term is a popular choice for borrowers who want more long-term certainty. Most borrowers tend to not think beyond three years.

This fixed rate term provides a stable monthly payment for three years, which can be beneficial for those who want to budget and plan ahead.

By opting for a three-year fixed rate, borrowers can avoid potential rate hikes and enjoy predictable mortgage payments.

Floating Mortgage

Floating mortgages offer flexibility in repayment, allowing you to pay off the loan without incurring any costs.

They can also be set up as revolving credits or offset mortgages, giving you more control over your loan.

Floating rates tend to be more expensive than fixed rates, but they're not locked into a specific rate for a long time.

This means you can take advantage of falling interest rates without being stuck with a higher rate.

A floating mortgage is a good option if you're not sure how long you'll be in your home, or if you want to be able to make extra payments towards your loan.

They can be a good choice if you're on a variable income or if you're not sure what the future holds.

Lender Options

You've got a lot of options when it comes to choosing a lender in New Zealand. There are over 20 banks and lenders to choose from, with different products and interest rates to suit your needs.

You can choose from a range of products, including Standard, Choices Floating, Residential, and many more. Some lenders offer specialty products like Blueprint to Build and Flexi, which may have specific lending criteria for owner-occupied and new build loans.

Some lenders also offer offset and revolving credit options, such as Total Money Offset and Revolving Home Loan.

Types of Lenders

You've got options when it comes to choosing a lender for your mortgage. Banks and non-bank lenders are two main types of lenders.

Banks tend to have lower interest rates but tighter lending criteria, making it harder to get a mortgage approved.

Non-bank lenders, on the other hand, have looser lending criteria but charge higher interest rates. For instance, Resimac's 1-year interest rate is 1.55% higher than Westpac's.

Non-bank lenders are a good option for business owners, borrowers with bad credit, investors with large portfolios, and anyone who struggles to get a mortgage from a bank.

Here are some groups that might find non-bank lenders more suitable:

  • Business owners
  • Borrowers with bad credit
  • Investors with large portfolios
  • Anyone who struggles to get a mortgage from a bank

Keep in mind that non-bank lenders can charge significantly higher interest rates. For example, Resimac's 3-year interest rate is 1.24% higher than Westpac's.

The New Zealand mortgage market has seen a dramatic shift in recent months, with borrowers locking in two-year terms as banks roll out competitive 4.99% interest rates.

According to the Reserve Bank, 89.5% of new owner-occupier loans were either floating or fixed for less than a year in January. However, this trend has since undergone a profound transformation.

The 4.99% rate has been a game-changer, with everyone switching from short terms to the traditional two-year option, which New Zealanders have loved for decades.

This shift occurred as borrowers initially positioned themselves for anticipated OCR cuts and now that these cuts have materialised, they're locking in longer terms.

The interest rate differential is driving this behaviour, with major banks advertising six-month rates at 5.79% or 5.89%, making the two-year option at 4.99% significantly more attractive.

60% or 70% of actual dollars is going into two-year terms, with most borrowers splitting their loans between combinations of one-year, two-year, or three-year terms.

Borrowers should focus on minimising interest costs over the life of their mortgage rather than trying to time the market perfectly.

Choosing a Mortgage

You can fix a large part of your mortgage to know what your repayment will be, but leaving a part on floating can be beneficial if you want to make extra payments without paying early repayment fees.

Many borrowers opt for a fixed mortgage, but it's essential to consider the potential risks of being locked into a high interest rate in the future.

The bank with the lowest interest rates will change over time, making it challenging to compare rates.

ANZ, ASB, BNZ, and Westpac all offer a 1-year rate of 4.49%, but it's not about choosing the lowest interest rate.

The key message is that banks offer different rates depending on how long you fix for, so it's crucial to consider your predictions about future interest rates.

In a few years, you might find you're locked into an expensive interest rate if you choose a longer term interest rate that's cheaper today.

Using a mortgage broker can be beneficial in negotiating a cheaper interest rate.
