The home loan process for building

Building your home can be an exciting project and a great way to stamp your personality on your home. Below is a step-by-step guide on how the home loan process works.


1. How much can I afford?

Work out how much you could borrow

Get an idea of how much you could borrow based on some quick questions about your financial situation.


Deposit options

The amount you’re able to borrow may depend on the amount of your deposit. Find out more about home loan deposit options.


Getting a pre-approval

At ANZ we can pre-approve your home loan – so you can look for a home with confidence.


2. Planning your build

Working out your finance options

When you're building, your home loan is approved for the full amount, but you draw it down in instalments as the building work progresses (your building contract will set out a payment schedule).

To find out more about how this process works, contact us.

Getting a lawyer

We strongly recommend you get your lawyer involved as early as possible.

Confirm the section

Once you have the section you’d like to build on, you’re ready to start planning.

Consider how you will manage the project

There's a lot to consider when managing a building project – is this something you’ll manage yourself? Or will you engage a professional project manager, builder or building company to do it for you?

Find the right architect, designer or company

Before you start the build process, you’ll want to ensure you find the right architect or building company.

The building contract

Written contracts for residential building work costing $30,000 or more (including GST) are compulsory before work starts. This is a good way to protect yourself, and it ensures everyone’s clear about what’s been agreed upon – and what happens if things don't go to plan. It’s also a good idea to get your lawyer to review the contract beforehand.

Obtaining building and resource consent

You'll need to obtain a building consent from your local council before building can start. Depending on your particular home and what you're proposing to build, you may also need to obtain resource consent.

In most cases your architect, designer, builder or building company will assist with these applications. If you're going to submit the applications yourself, contact your local council for information on how to apply.

3. Building

Managing the building phase

Whether you're managing the building yourself or not, you should keep a close eye on the building as it progresses. Ensure you keep a record of all invoices, variations, payments and correspondence.

Managing the completion phase

When the work’s finished, make sure that:

  • The builder leaves the site clean and tidy, and that you have all product manuals and guarantees you need.
  • A final building inspection is completed.
  • The Code of Compliance Certificate is issued – this certifies that the building complies with the building code. It's important this is signed off as it could cause problems with your insurance or with resale if you don't have it.
  • Contact your local council for more information on inspection and consent requirements for your area.

4. Managing your loan

Now your build is complete and you've drawn down all of your instalments, we can work with you to decide the best way to structure your loan. It's also a good time to review or organise your house, contents and life insurance.

Manage your loan

Once your loan is set up with ANZ, you can track it using ANZ Internet Banking or the goMoney app.
