How to grow your first home deposit

4 MIN READ 28/08/2025
Once you’ve set your deposit goal, it’s time to focus on growing your savings. Budgeting, saving strategies, and making the most of your KiwiSaver savings can help you stay on track and accelerate your progress towards home ownership.


Create a budget for your deposit savings
A structured budget is a powerful tool that helps you manage your finances and save effectively for your home deposit. 

Evaluate your expenses and prioritise your needs over wants. Cutting back on discretionary spending and redirecting those funds into your deposit savings can make a big difference over time. Following this approach helps ensure you’re consistently saving and keeping your financial plan on track.

To start creating your budget, use the Sorted Budget Planner. It’s a great resource to help you put a plan in place that works for you. 

Be purposeful with your budget
A great way to show the bank that you’re financially prepared for a mortgage is to ensure that the total amount you’re saving each month (excluding KiwiSaver contributions) plus your rent payments equals or exceeds what your mortgage repayments would be. This demonstrates to lenders that you can manage the financial commitment of a mortgage and strengthens your application.

Your budget isn’t a restriction but rather a tool to help you understand where your money is going. By using this understanding, you can prioritise your spending to align with your goals.

Strategies to boost your savings
Here are some practical tips:

  • Cut non-essential costs: Small changes can add up over time. Consider switching to a cheaper phone or internet plan, buying in bulk, cooking at home instead of dining out, cancelling TV subscriptions, and carpooling or taking public transport.
  • Stick to your savings rate:  Set up an automatic payment from your account to a high-interest savings account to make savings consistent, and don’t spend it or withdraw it once it’s there!
  • Manage debt: Avoid unarranged overdrafts and ensure credit cards are paid off monthly to prevent interest charges. Steer clear of taking on new debt and avoid buy-now-pay-later apps like Afterpay or Laybuy.  Watch this video to learn more about managing debt effectively.
  • Increase your income:  Look for opportunities to boost your earnings by asking for a pay rise, if you haven’t had a recent pay review, back yourself and start the conversation. You could also take on extra work or hours, sell items you no longer need, or rent out a spare room to help cover your current rent or living expenses.

Regularly reviewing and adjusting your budget is key to staying on track. Prioritise your deposit savings and maintain momentum.

Make the most of KiwiSaver
As long as you’ve been contributing to KiwiSaver for at least three years and intend to live in the home for at least the first 6 months, you’re eligible to withdraw all but $1000 of your KiwiSaver savings for your first home. Increasing your KiwiSaver contributions can be an effective way to build your deposit, as it’s automatically deducted from your income before, reducing the temptation to spend. 

Next steps
Take time to sit down and develop a detailed budget. Review your current expenses, identify areas for reduction, and allocate as much as possible towards your deposit savings.

If you’re planning to use your KiwiSaver savings for your home purchase, it’s also timely to ensure you’re on track by booking a meeting with a Haven financial adviser. They’ll help make sure your KiwiSaver investment aligns with your goals.
