Understanding the True Costs of Buying Your First Home in New Zealand

When you are preparing to buy your first home, most of the focus naturally goes toward saving a deposit and securing a mortgage. While these are critical parts of the journey, they are only one piece of the financial puzzle. Many first home buyers are caught off guard by the additional costs that arise both before settlement and after moving into their new home.

Understanding these costs early can make a significant difference to your experience. It allows you to budget more accurately, avoid financial stress, and make confident decisions throughout the process.

This guide walks through the key costs you should expect as a first home buyer in New Zealand, covering both pre-purchase expenses and the ongoing costs of homeownership.

If you are unsure where you currently sit in your journey, it can be helpful to map things out using the FHBC planning tool.

The Costs Before You Buy: Preparing for Purchase

Before you even receive the keys to your home, there are several important costs that come into play. These are often referred to as due diligence or pre-purchase costs, and they can be important for understanding the property and protecting your position before committing.

Legal Fees: Your First Line of Protection

Engaging a property lawyer or conveyancer is one of the first and most important steps in the process. Your lawyer will review the Sale and Purchase Agreement, ensure your interests are protected, and guide you through the legal aspects of the transaction.

Legal fees vary by lawyer, location, transaction type and complexity. As an indicative industry example, a first-home purchase may cost around $1,500 to $2,500 plus GST, but get a quote and check what is included.

Your lawyer will also handle tasks such as title searches, liaising with your lender, and managing settlement day. Legal review is important because the sale and purchase agreement and settlement documents can materially affect your rights and obligations.

Building Reports: Understanding What You're Buying

A building report provides an independent assessment of the property's condition. It can highlight structural issues, moisture problems, deferred maintenance, and other potential risks.

In New Zealand, building reports typically cost between $500 and $1,000, depending on the size and complexity of the property. While this may feel like an optional cost, it can be a useful due-diligence cost, especially where condition, moisture, maintenance, or unconsented-work risks matter.

A thorough building report may help uncover issues before you commit. It may also help with negotiation or decision-making, but the outcome depends on the property, contract, seller, and timing.

Valuation Reports: When the Bank Requires One

A registered valuation may be required by your lender, particularly if you are buying with a low deposit or purchasing a property that falls outside standard criteria.

Valuation costs vary by provider, property and lender requirements.

Not every purchase requires a valuation, but when it is required, your lender or adviser can explain what type of valuation is acceptable and when it must be ordered.

LIM Reports and Property Checks

A Land Information Memorandum, commonly known as a LIM report, provides detailed information from the local council about the property. This can include zoning, consents, flood risks, and any known issues.

Some properties will already have a LIM report available from the vendor. If not, you may need to request one yourself. LIM cost and turnaround vary by council and urgency. For example, Tauranga City Council's 2026/27 residential LIM fees list a 10-day email service at $395 and a 5-day email service at $680, so check the relevant council fee schedule.

Alongside the LIM, you may also incur costs for additional checks such as title searches or specialist reports, depending on the property.

Insurance Before Settlement

One cost that is often overlooked is the requirement to have house insurance in place before settlement. Most banks and lenders require insurance before confirming the loan or settlement, as the home serves as security for the loan. Confirm the timing and evidence required with your lender, insurer and lawyer.

The cost of insurance will depend on factors such as the property's location, construction type, and replacement value.

A useful starting point to estimate your rebuild cost is the Sum Insured Calculator.

Deposit and Cash Contribution Planning

While your deposit is not a “cost” in the traditional sense, it is important to understand how much cash you will need available alongside your deposit.

This includes covering all of the above expenses, which are typically paid before settlement. Many first home buyers underestimate how much cash buffer they need outside of their deposit.

The Costs After You Buy: Living in Your First Home

Once you have settled on your home, a new set of ongoing costs begins. These are the expenses that come with homeownership and are essential to factor into your long-term budget.

Rates: Your Ongoing Contribution to Local Services

Rates are a form of property tax paid to your local council. They fund services such as infrastructure, waste management, and community facilities.

Rates can be thousands of dollars a year and vary by council, property value, and location. Use the council property or rates search for the specific property.

This cost is ongoing and should be factored into your regular budget.

Home Insurance: Protecting Your Biggest Asset

Home insurance is often required by your lender and can also help protect against major insured events.

Annual premiums can be thousands of dollars and vary by location, construction, cover, insurer and risk factors. Get current quotes for the specific property.

It is worth reviewing your insurance regularly to ensure it continues to meet your needs.

Mortgage Repayments: Your Largest Financial Commitment

Your mortgage repayments will likely be your biggest ongoing expense. These repayments will depend on your loan amount, interest rate, and loan structure.

Understanding how repayments may change over time is critical, particularly when interest rates are refixed.

Using the FHBC mortgage calculator can help you model this clearly.

Maintenance and Repairs: Planning for the Unexpected

One of the most underestimated aspects of homeownership is maintenance. Unlike renting, homeowners are responsible for all upkeep and repairs.

Some buyers use a percentage-of-value rule of thumb for maintenance, but actual costs depend on age, construction, condition, weather exposure, body-corporate coverage, and whether major items are due.

While this may not be spent every year, costs such as roofing, plumbing, painting, and general wear and tear will arise over time.

Utilities and Everyday Living Costs

Once you move into your home, you will take on full responsibility for utilities such as electricity, water, internet, and potentially gas.

These costs can vary depending on your household size and usage but are an important part of your ongoing financial commitments.

You may also find that your overall spending patterns shift as a homeowner, particularly in the early stages when furnishing and setting up your home.

Body Corporate Fees (If Applicable)

If you are purchasing an apartment or townhouse, you may need to pay body corporate fees. These contribute to shared expenses such as building insurance, maintenance, and common area upkeep.

These fees can vary widely and should be carefully reviewed before purchasing.

Planning Ahead: Avoiding Financial Stress

Understanding the full range of costs associated with buying your first home allows you to plan ahead and make informed decisions. It also helps you avoid stretching your budget too far on the purchase price, leaving little room for other expenses.

Taking the time to build a detailed budget, including both upfront and ongoing costs, can give you confidence in your decision.

A great place to start is the FHBC budget tool, which helps you map your income, expenses, and future homeownership costs.

The Real Advantage Comes From Being Prepared

Buying your first home is one of the most exciting milestones you will achieve, but it is also one of the most financially complex. The deposit and mortgage are only part of the story. The true success lies in understanding everything that surrounds them.

When you factor in legal fees, building reports, valuations, insurance, rates, and ongoing maintenance, you gain a much clearer picture of what homeownership really looks like.

Many buyers find it easier to navigate the journey when they prepare early, understand the main costs, and build a buffer for the unexpected.

By approaching the process with clarity and a plan, you are not just buying a home, you are creating a stable financial foundation that will support you for years to come.
