Unexpected expenses can happen to anyone: a car repair, dental bill, appliance replacement, or a temporary drop in income. Having accessible savings set aside for these events can reduce financial stress and help avoid relying on high-interest debt.
Sorted’s new Buffer Builder App is a free tool designed to make building an emergency fund easier. It helps you save gradually, using small automated actions that fit around everyday life.
How it works
You can choose one or more ways to add to your buffer:
The money stays in a bank account in your own name. The app is designed to transfer funds only into your nominated buffer account—you remain in control and can adjust or pause the settings at any time. It is currently available for customers banking with ANZ, ASB, BNZ, Kiwibank and Westpac.
Why an emergency fund matters
A cash buffer is not intended to replace insurance, long-term investments, or KiwiSaver. It is a readily available pool of money for genuine short-term surprises.
Even a modest starting goal can make a difference. For example, beginning with $500 to $1,000 may help cover a smaller unexpected cost. Over time, many households aim to build enough accessible savings to cover several months of essential expenses, tailored to the stability of their income, debt commitments, insurance arrangements and family circumstances.
A simple next step
If you have not yet started an emergency fund, consider setting aside a small amount on each payday. Consistency matters more than the initial amount. A regular $20 or $50 contribution can grow into a useful financial cushion over time.
Sorted’s Buffer Builder App is free to use and is part of Sorted’s wider range of independent money tools and guidance for New Zealanders. It uses open-banking connections through Akahu to support account insights and automated saving, with user permissions and controls applying to those connections.
