How to Automatically Split Your Pay Into Multiple Accounts in NZ
Four practical methods to divide your pay across savings, bills, and spending accounts the moment it arrives. Step-by-step instructions for each approach, with honest pros and cons.
25 March 2026
You know you should be splitting your pay into different accounts. Savings here, bills there, spending money separate. Every personal finance guide says the same thing. But knowing and doing are two very different things.
Most people get paid, see one lump sum in their transaction account, and spend from that single pot until the next payday. The savings transfer gets forgotten, the bills account runs short, and the cycle repeats.
The good news is that there are several ways to automate pay splitting in New Zealand, from completely free options to purpose-built apps. This guide covers all four methods with step-by-step instructions so you can pick the one that fits your situation.
Why Splitting Your Pay Actually Works
Pay splitting works because of a simple behavioural principle: you spend what you see. When your entire pay sits in one account, your brain treats all of it as available spending money. But when $500 has already moved to a bills account and $200 to savings before you even open your banking app, your spending naturally adjusts to what remains.
A common split for New Zealanders
50% to bills and essentials (rent, power, groceries), 30% to everyday spending, and 20% to savings and debt repayment. This is the 50/30/20 rule, and it is one of the easiest frameworks to automate with pay splitting.
The key is making the split happen automatically, before you have a chance to spend it all. Here are four ways to do that in New Zealand.
Method 1: Ask Your Employer to Split Your Pay
The simplest and cheapest method is asking your employer to deposit your pay into multiple bank accounts. Most New Zealand payroll systems support this, though not every employer offers it.
How to set it up
Talk to your payroll or HR team
Ask if they can split your pay across multiple bank accounts. Common payroll systems like MYOB, Xero, and SmartPayroll all support multiple bank accounts per employee.
Provide your account details
Give them the bank account numbers for each account you want to split into. You will need your account number, bank name, and branch for each.
Specify the split amounts
Tell them exactly how much or what percentage goes to each account. Typically you set fixed amounts for secondary accounts and the remainder goes to your main account.
Wait for the next pay cycle
Changes usually take effect from the next pay run. Check that the amounts land correctly and follow up with payroll if anything looks off.
Pros
- - Completely free
- - Money is split before it even reaches you
- - Zero ongoing effort once set up
- - Works with any bank in New Zealand
Cons
- - Not all employers offer it
- - Usually fixed dollar amounts, not percentages
- - Awkward to change frequently (need to ask HR each time)
- - Does not adjust when your pay varies (overtime, fewer hours)
Best for: People with a fixed salary who get paid the same amount every time and are happy with a set-and-forget fixed dollar split.
Method 2: Set Up Bank Automatic Payments
Every major New Zealand bank lets you schedule automatic payments (APs) that transfer money between accounts on a set date. You can schedule these to run on your payday to simulate pay splitting.
How to set it up at each bank
ANZ Internet Banking or goMoney app
Go to Pay and Transfer, then Automatic Payments. Choose your transaction account, enter the destination account, set the amount and frequency (weekly, fortnightly, or monthly) to match your pay cycle.
ASB FastNet Classic or Mobile
Navigate to Payments, then Automatic Payments. Select the from and to accounts, set the recurring amount and schedule. ASB also lets you set up automatic transfers between your own ASB accounts instantly.
BNZ Online Banking or App
Go to Payments, then Automatic Payments. Set up recurring transfers to your savings or bills accounts. BNZ also offers "Goals" accounts which work well as split destinations.
Westpac One Online Banking or App
Head to Payments, then Scheduled Payments. Set up recurring transfers on your pay frequency. Westpac also has a "Spend Tracker" feature that helps you monitor where your money goes after splitting.
Kiwibank Internet Banking or App
Go to Payments, then Automatic Payments or Scheduled Transfers. Set the amount, frequency, and destination account. Kiwibank also has Goal Accounts that you can set up as split targets.
Pros
- - Free at all NZ banks
- - Easy to set up and change yourself
- - No need to involve your employer
- - Can split to multiple accounts at once
Cons
- - Fixed amounts only, not percentages of your actual pay
- - Runs on a schedule, not when pay actually arrives
- - Risk of overdraft if pay is late or AP runs before pay lands
- - Cannot split across different banks easily (slower transfers)
Best for: People with regular pay dates who keep all their accounts at the same bank, and who earn a consistent amount each pay cycle.
Method 3: Manual Transfers on Payday
The most flexible but least reliable method. Every time you get paid, you open your banking app and manually transfer money to your various accounts.
How to make it work
Set a phone reminder for payday
Create a recurring calendar event or alarm for the morning of each payday.
Check your pay amount
Log into your banking app and confirm how much you received.
Calculate your splits
Work out the amounts for each account based on your budget (for example, 50% to bills, 20% to savings, 30% stays for spending).
Make the transfers
Manually transfer each amount to the right account. This might take 3 to 5 minutes depending on how many accounts you use.
Pros
- - Completely free
- - Maximum flexibility to adjust every pay cycle
- - Can adapt to variable income
- - Works across any banks
Cons
- - Requires willpower and discipline every single payday
- - Easy to skip, forget, or "do it later" (then never do it)
- - Tedious if you split across 3 or more accounts
- - Most people stop doing it within a few months
Best for: People who enjoy hands-on control and have strong financial habits already. Honestly, if you were the kind of person who could do this reliably every payday, you probably would not be reading this article.
Method 4: Automatic Pay Splitting with PayDay
PayDay is a New Zealand app built specifically to solve the pay splitting problem. It detects when your pay arrives, then automatically splits it across your accounts based on rules you set. No manual transfers, no scheduled payments that might fire at the wrong time, and no need to ask your employer for anything.
How it works
Connect your bank accounts
Link your accounts from any NZ bank through Akahu, a secure open banking platform. You can connect accounts from ANZ, ASB, BNZ, Westpac, Kiwibank, and other NZ banks all in one place.
Set up your split rules
Define where your money goes using percentages or fixed amounts. For example: 20% to savings at ASB, $400 to a bills account at ANZ, and the rest stays in your spending account at BNZ.
PayDay detects your pay
When your salary, wages, or any income you have configured lands in your account, PayDay recognises it instantly. No need to tell it you got paid.
Automatic splitting happens
Your money is distributed across your accounts according to your rules. You get a notification confirming everything has been split. Done.
Pros
- - Truly automatic: triggers when pay actually arrives, not on a schedule
- - Percentage-based splits that adjust to variable income
- - Works across different banks (ANZ savings + BNZ spending + ASB bills)
- - Change your rules anytime without contacting anyone
- - No risk of overdraft since it waits for your pay to land
Cons
- - Not free (subscription-based, though there is a free trial)
- - Requires connecting your bank accounts via Akahu
- - Currently in early access (join the waitlist)
Best for: People with variable income (casual, shift work, freelancing, commission), people who bank with multiple banks, and anyone who has tried the other methods and found them too rigid or too easy to forget.

Which Method Should You Choose?
The honest answer depends on your situation:
Salaried with one bank and a helpful employer
Start with employer salary splitting. It is free, it works, and it requires zero ongoing effort. Ask your payroll team this week.
Regular pay, employer will not split, one bank
Bank automatic payments are your next best option. Set them up once, match them to your pay cycle, and let them run. Just make sure the timing aligns with when your pay actually lands.
Variable income, multiple banks, or tried and failed other methods
PayDay is built for this. If you work casual or shift work, earn commission, freelance, or just want to split across banks like ANZ and ASB without thinking about it, PayDay handles it automatically based on what you actually earn each pay cycle.
The Bottom Line
Pay splitting is one of the most effective money management strategies available, and the best method is whichever one you will actually stick with. If asking your employer works for you, brilliant. If bank automatic payments do the job, that is great too.
But if you have tried those approaches and found yourself slipping, or if your income varies too much for fixed-amount transfers, or if you bank across multiple institutions, then automatic pay-triggered splitting with PayDay removes the friction entirely.
The important thing is to start. Pick any method from this list, set it up today, and your future self will thank you for it.
