Tracking rates from every major New Zealand lender
The market
Every OCR announcement eventually works its way into mortgage rates. RateWise tracks both daily, so you know when the rate you fixed at stops being a good deal. This chart is drawn live from the announcements we've logged.
The platform
RateWise brings your mortgage, your rates and your next decision together, so the smart move is always obvious.
Dashboard
A mortgage health score grades how hard your loan is working and points you to your next move, with your properties, equity, income and expenses in the same view.
Rates
Every major New Zealand lender, refreshed daily, with the context to tell whether a rate is worth moving for and an alert when it is.
Planning
Run the numbers on any decision with calculators and planners built on real New Zealand lending criteria, not generic formulas.
Mortgage Health Score
RateWise keeps a constant eye on your mortgage and the market, then turns it into one clear score and a short list of things worth doing. No spreadsheets, no guesswork.

RateWise Guide
The Guide sits quietly at the bottom of the app until you need it. Ask about your renewal, today's rates or what a restructure would cost, and it answers in plain English with your own numbers.
The Guide offers general guidance, not regulated financial advice. Talk to a licensed adviser before big decisions.
AI connectors
RateWise speaks MCP, the open standard AI assistants use to plug into your tools. Link your account and your assistant can check today's rates, run the calculators and keep your details up to date, all from a single chat.
The toolkit
Whether you are buying, refixing or weighing up a refinance, every tool is built on real New Zealand lending data.
See what switching could save you, break-even point and fees included, using current market rates rather than guesswork. Compare scenarios across multiple lenders and see monthly and lifetime savings before you commit to anything.
