PayDay vs Booster BudgetingNZ
Two Kiwi-built money apps, two different jobs. Booster helps you plan envelopes and track goals. PayDay actually moves the money. Here's how to choose - or use both.
Plan vs execute
Booster BudgetingNZ helps you plan - building envelopes, setting goals, and tracking progress. PayDay is the execution layer - when your pay lands, it automatically splits across the accounts you've chosen. Together they make your plan actually happen.

Envelopes vs automated splits
Two different flavours of "give every dollar a job" - and why they pair so well.
Booster: envelopes inside one view
Booster BudgetingNZ uses the classic envelope method - you allocate portions of your income to categories like groceries, rent, power and fun money. You see, in one screen, how much is left in each envelope for the period.
The money stays in your bank accounts - Booster just labels it. That's efficient for tracking but relies on you not overspending an envelope, since nothing physical is preventing you.
PayDay: real money, real accounts
PayDay moves actual money into actual accounts based on your split rules. If you've set 40% bills, 30% savings, 30% spending, that is exactly what happens the moment your pay arrives.
The friction of having money physically separated - in different accounts or even different banks - is part of the point. It's much harder to overspend "spending money" when savings are already moved out.
Pricing comparison
Simple, NZD, honest.
PayDay pricing
Standalone - you're never pushed toward another product. See full pricing.
Booster BudgetingNZ pricing
Free because it sits inside Booster's broader financial services business, which includes KiwiSaver and managed funds. That's not bad - just worth knowing.
Who should use which
The quick answer based on what you're trying to fix.
Choose PayDay if...
- -You've already tried envelope budgeting and just don't move the money in time
- -You want separation that's physical, not just labels on a screen
- -You have accounts at more than one bank
- -You want an app that's not trying to sell you KiwiSaver or other products
- -Your pay day feels chaotic and you want it to be a non-event
Choose Booster BudgetingNZ if...
- -You want a free app and aren't ready to pay for automation
- -You like the envelope method and enjoy checking in on categories
- -You already trust Booster as your KiwiSaver provider
- -Tracking goals is more motivating for you than physical separation
- -You want to start simple and manual before you automate
The honest verdict
Booster BudgetingNZ and PayDay are built for New Zealand and solve different parts of the same problem. Booster is free, envelope-based and great for visualising whether you're living within your plan. It leans on your discipline to actually stick to the envelopes.
PayDay is the automation layer. Instead of hoping you won't dip into grocery money for drinks out, PayDay physically moves savings into a separate account the moment pay lands. It's harder to overspend money that isn't in front of you.
The two apps complement each other: plan your envelopes in Booster, then set up PayDay to actually move the real dollars to match. If you can only pick one, the right answer depends on whether your problem is "I don't know my numbers" (use Booster) or "I know my numbers but never act on them" (use PayDay).
Both are legitimate Kiwi products from teams who understand the local market. You won't go wrong with either - and together they're better than either alone.
PayDay vs Booster BudgetingNZ FAQs
Common questions from Kiwis weighing up the two.
Can I use both PayDay and Booster BudgetingNZ together?
Yes - and they complement each other really well. Booster BudgetingNZ is great for planning envelopes, allocating money to categories, and tracking goals. PayDay handles the automated execution - the moment your pay lands, it splits into the correct accounts without you doing anything. Plan in Booster, execute with PayDay.
Which is cheaper, PayDay or Booster BudgetingNZ?
Booster BudgetingNZ is free to use - it's supported by Booster's broader financial services business, including their KiwiSaver products. PayDay is also free while pre-launch, with a paid Pro tier in development. If budget is your only criterion, Booster's free app is hard to beat. The real question is whether free-but-manual or paid-but-automated suits you better.
Does Booster BudgetingNZ work with NZ banks?
Booster BudgetingNZ is built in New Zealand for New Zealanders and supports major NZ banks for reading transactions and categorising spending into envelopes. PayDay also supports all major NZ banks (ANZ, ASB, BNZ, Westpac, Kiwibank and others) via Akahu. The key difference isn't bank coverage - both have it - it's what each app does with the connection.
Which has better security?
Both use secure open banking connections, so your banking credentials are never stored by the app. Booster BudgetingNZ is backed by Booster, an established NZ licensed financial services provider. PayDay uses Akahu, New Zealand's regulated open banking platform, for both read access and authorised payment initiation. Both are trustworthy options built for New Zealand.
Can Booster BudgetingNZ automatically split my pay?
No. Booster BudgetingNZ is envelope-style budgeting and goal tracking - it helps you plan and see whether you're on track, but it does not physically move money between your accounts. That's exactly the gap PayDay fills. You set up the envelopes/goals in Booster, and let PayDay handle moving the right amounts into the right accounts every payday.
Do I have to be a Booster KiwiSaver member to use BudgetingNZ?
No, Booster BudgetingNZ is generally available to anyone in New Zealand, not just Booster KiwiSaver members. That said, Booster's broader ecosystem is part of why the app is free - it's a useful front-door to Booster's other products. PayDay has no such tie-in; it's a standalone pay automation app and doesn't try to sell you KiwiSaver or investments.
Plan in Booster. Execute with PayDay.
Envelopes are useful, but only if the money actually moves. PayDay does that part - automatically, every payday, across every NZ bank you use.
