Home Improvement Loans in New Zealand – Compare the Right Option for Your Renovation

Renovating your home can improve how you live, increase property value, or prepare your house for future resale. The challenge for many homeowners is working out how to fund those improvements without overpaying or choosing the wrong loan type.

At OneStop Financial Solutions, our mortgage brokers help you compare home improvement loans in New Zealand. From personal renovation loans to mortgage top-ups and construction lending, we help you choose the option that best fits your plans and budget.

Funding Home Improvements the Smart Way

Whether you’re planning to renovate a kitchen, extend your living space, upgrade a bathroom, or complete a full home extension, there are multiple ways to finance home improvements in New Zealand.

Many homeowners assume a personal loan is their only option. In reality, lenders offer several structures depending on:

  • The size of your project
  • Whether you have equity in your existing loan (or a paid off home)
  • How long you want to repay the loan

A home improvement loan allows you to spread the cost over time, making renovations more manageable without draining your savings.

Home Improvement Loan Options in New Zealand

There are two main ways to fund renovations through NZ lenders: unsecured loans and secured lending against your home.

Home Loan Top-Up or Equity Loan (Secured)

A mortgage top-up uses your home as security and is one of the most cost-effective ways to fund larger renovations.
This option is commonly used for:

  • Kitchen and bathroom renovations
  • Structural changes or extensions
  • Multiple renovation projects at once

How it works:

  • Borrowing is based on available equity in your property
  • Funds are added to your existing mortgage or refinanced
  • Interest rates are generally lower than personal loans

What to consider:

  • Repayment terms can be 20–30 years
  • Monthly repayments may be lower, but interest is paid over a longer period
  • Your home is security for the loan

For medium to large projects, a mortgage top-up is often the best long-term option.

Construction Loans for Major Renovations

For significant renovations or extensions, some lenders offer construction-style lending.
Best suited for:

  • Large renovations or structural rebuilds
  • Projects completed in stages

How it works:

  • Funds are released progressively as work is completed
  • Interest is often charged only on the amount drawn
  • Requires detailed plans and builder quotes

This structure helps manage cash flow on complex projects.

Personal Loan for Home Renovations (Unsecured)

A personal loan for home improvements is not secured against your property.
This option is often suitable for:

  • Smaller to medium renovation projects
  • Cosmetic upgrades (painting, flooring, appliances, landscaping)
  • Homeowners with limited equity

How it works:

  • Borrowing limits vary by lender
  • Fixed interest rate and fixed repayments
  • Typical loan terms range from 3–7 years

Things to consider:

  • Interest rates are usually higher than mortgage lending
  • Borrowing limits are lower than secured loans

For smaller renovation budgets, a personal loan can be a simple and fast solution.

What to Do Before You Apply for a Home Improvement Loan

  • Plan Your Renovation: Outline the work you want completed and gather rough cost estimates. Larger projects may require builder quotes or plans.
  • Understand What You Can Afford: Review your income, expenses, and existing debts. Think about how much you’re comfortable repaying monthly, and for how long. Use our mortgage repayment calculator to estimate repayments and timeframes. 
  • Speak With a Renovation Loan Specialist: We’ll assess your mortgage, equity position, and renovation plans, then compare suitable loan options across our lender network.

We first worked with Matt Willoughby and the team at OneStop a couple of years ago as first home buyers, and they were absolutely fantastic. They made what felt like the impossible happen and helped get my partner and me over the line.

Since then, we've continued working with them including taking the plunge into "adulting" by sorting out both life insurance and health insurance. Matt and the team made the whole process simple and easy to understand, walking us through every step.

We've now used them for all our insurance needs over the years, and they’ve always gone above and beyond. Such a great team and genuinely helpful, professional, and always with your best interest at heart. Couldn't recommend them more highly!

Frequently Asked Questions About Home Improvement Loans

A home improvement loan is finance used to renovate or upgrade a property. Depending on how much you need to borrow, this can be a mortgage based structure, or an unsecured personal loan. Our blog post on top up loans vs home improvement loans explains this further.

Borrowing limits depend on income, credit profile, and for secured loans, available home equity.

A renovation loan is often unsecured, while a mortgage top-up uses your property as security and usually offers lower interest rates. Learn more about how home renovation loans work.

KiwiSaver cannot be used for home improvements. Read our blog post on when you can use KiwiSaver.

If your home improvement loan is secured against your home and you sell, the loan will be paid off from the proceeds of the sale. If your home improvement loan is an unsecured personal loan, this remains your responsibility regardless of property ownership.
