Best Automatic Savings Apps in NZ (2026 Comparison)
We tested and compared the top ways to automate your savings in New Zealand. Here is what actually works, what does not, and which option fits your situation best.
28 March 2026
If you have ever searched for "best savings app NZ," you have probably noticed something frustrating: most results are either about investing apps or generic budgeting tools. Very few actually help you automate the simple act of moving money into savings when you get paid.
This guide cuts through the noise. We are comparing the actual options available to New Zealanders in 2026 for automating savings, from free bank tools to dedicated apps. Each has genuine strengths and weaknesses, and the best choice depends entirely on what you are trying to achieve.
What to Look for in a Savings Automation Tool
Before we compare specific options, here is what actually matters when choosing a savings automation tool:
Trigger type
Does it save on a fixed schedule, or when your pay actually arrives? Pay-triggered automation is far more reliable, especially if your income varies or your pay date shifts.
Percentage vs fixed amount
Fixed-amount transfers break when your income changes. Percentage-based savings scale with your earnings, so you always save the right proportion.
Multiple account support
Can you split money to several accounts at once? Most people need at least an emergency fund and one or two sinking funds running simultaneously.
Security and bank access
How does the tool connect to your bank? Look for open banking APIs (like Akahu in NZ) rather than screen scraping, which is less secure and less reliable.
Cost
Some tools are free, others charge a monthly fee or take a percentage. Make sure the cost does not eat into the savings you are trying to build.
The 5 Best Ways to Automate Savings in NZ (2026)
Here is an honest look at each option, including who it is best suited for and where it falls short.
1. Bank Automatic Payments (Free)
Every major NZ bank (ANZ, ASB, BNZ, Kiwibank, Westpac) lets you set up automatic payments or scheduled transfers between your own accounts. This is the simplest option and costs nothing.
Pros
- Completely free
- No third-party app needed
- Simple to set up in your banking app
- Reliable and well-understood
Cons
- Fixed amounts only (no percentage of pay)
- Fixed schedule (does not adapt to actual pay date)
- Can overdraw if pay is late or lower than expected
- Only works within one bank
Best for: People with a stable salary, consistent pay dates, and accounts at a single bank. If your income varies or you get paid irregularly, bank auto-transfers can cause more problems than they solve.
2. Sharesies Auto-Invest ($3/month or 0.5% fee)
Sharesies is NZ's most popular micro-investing platform, and it offers an auto-invest feature. You set a recurring amount, choose your funds or shares, and it invests automatically on a regular schedule.
Pros
- Combines saving and investing in one step
- Good range of NZ and international funds
- Low minimum investment ($1)
- Well-designed app, easy to use
Cons
- Investing, not saving (your balance can go down)
- Not suitable for emergency funds or short-term goals
- Fixed schedule, not pay-triggered
- Fees reduce returns on small balances
Best for: People who already have an emergency fund and want to build long-term wealth. Sharesies is an investing tool, not a savings tool. If you need the money within the next 1-3 years, the market risk makes it unsuitable.
3. Kernel Wealth Auto-Invest (0.25% annual fee)
Kernel is another NZ-based investment platform with an auto-invest feature. It focuses on index funds and has some of the lowest fees in the NZ market, making it popular with passive investors.
Pros
- Very low management fees (0.25%)
- High-quality NZ and global index funds
- Auto-invest with customisable frequency
- Clean, straightforward interface
Cons
- Investing, not cash savings
- $100 minimum per auto-invest order
- Fixed schedule, not triggered by pay
- Withdrawals take a few business days
Best for: Long-term investors who want a set-and-forget approach to wealth building. Like Sharesies, this is an investment platform, not a savings automation tool. Great for money you will not need for 5+ years.
4. Dosh (Free)
Dosh is a NZ-built app that rounds up your everyday purchases and saves the spare change. If you spend $4.50 on a coffee, it rounds up to $5.00 and moves the extra $0.50 to savings. It works with most NZ banks through open banking.
Pros
- Painless way to start saving
- Works across multiple NZ banks
- Free to use
- Good for building a savings habit
Cons
- Round-ups save very small amounts
- No pay-splitting or percentage-based saving
- You will not build serious savings from round-ups alone
- No control over how much is saved per pay cycle
Best for: People who want to get started with saving but find it hard to commit to larger amounts. Dosh is a great first step, but you will likely outgrow it quickly. Think of it as training wheels for savings.
5. PayDay - Automatic Pay Splitting (Coming 2026)
PayDay takes a different approach from everything above. Instead of fixed schedules or round-ups, it detects when your pay arrives and instantly splits it across your accounts based on rules you set. You choose percentages or fixed amounts, and the transfers happen within minutes of getting paid.
Pros
- Pay-triggered (works the instant you get paid)
- Percentage-based or fixed amount splits
- Split to multiple accounts at once
- Works across NZ banks via Akahu
- Handles variable income and irregular pay dates
Cons
- Not yet launched (currently in waitlist phase)
- Not an investing tool (savings only)
- Requires Akahu-supported bank accounts
Best for: Anyone who wants to automate the "pay yourself first" method properly. Especially valuable for people with variable income, irregular pay dates, or accounts at multiple banks. PayDay does one thing and does it well: it makes sure your money is in the right accounts before you can spend it.

Saving vs Investing: Know the Difference
One important distinction that often gets lost in "best savings app" articles: saving and investing are not the same thing.
The Key Difference
Saving is moving money to a safe place where it will not lose value (bank savings accounts, term deposits). You do this for emergency funds, short-term goals, and money you cannot afford to lose. Investing is putting money into assets that may grow over time but can also drop in value (shares, funds, property). Sharesies and Kernel are investing tools. Bank auto-payments, Dosh, and PayDay are savings tools. Most people need both, but saving comes first.
Which Option Is Right for You?
The honest answer: it depends on where you are in your financial journey.
Just starting out?
Start with Dosh for round-ups and a bank auto-transfer for a small fixed amount. This builds the habit with minimal commitment.
Stable income, want serious savings?
PayDay is ideal. Set percentage-based splits to automatically distribute every pay across your savings accounts, emergency fund, and spending money.
Variable or irregular income?
PayDay is the only NZ option that properly handles this. Percentage-based, pay-triggered splits mean you save proportionally no matter what you earn.
Ready to invest for the long term?
Use PayDay for your savings splits, then set up Kernel or Sharesies auto-invest separately for money you will not need for 5+ years. They solve different problems and work well together.
Why Pay-Triggered Splitting Matters
The fundamental weakness of every other option on this list is timing. Bank auto-payments run on a fixed schedule. Sharesies and Kernel invest on set dates. Dosh only saves when you spend. None of them respond to the most important financial event in your life: getting paid.
When your savings happen the instant your pay arrives, three things change:
- You never see the money in your spending account, so there is no temptation to spend it.
- It scales with your income, so a big pay means bigger savings and a smaller pay means you are not overcommitting.
- It works regardless of when you get paid, so public holidays, shifted pay runs, and irregular schedules are all handled automatically.
This is not a marginal improvement. It is a fundamentally different approach to savings automation, and it is the core of what PayDay is built to do.
The Bottom Line
There is no single "best" savings app for everyone. Bank auto-transfers are a solid free option for people with stable incomes. Sharesies and Kernel are excellent for long-term investing. Dosh is a gentle way to start building savings habits.
But if what you really want is to automate the "pay yourself first" method - to have your pay split into the right accounts the moment it lands, every single time, without thinking about it - that is exactly what PayDay is designed for.
The best approach for most Kiwis is a combination: use PayDay for pay-splitting and short-term savings, and layer on an investing app like Kernel or Sharesies once your emergency fund is sorted. Automation is not about picking one tool. It is about building a system that works.
