HR software development in Hastings for a workforce that goes from 60 to 400 people in three weeks
Custom HR (Human Resources) and workforce software for a Hastings packhouse or grower costs NZ$55,000 to NZ$150,000 and takes 12 to 24 weeks. It earns its keep on three things generic products handle badly: RSE crew records with accommodation and pastoral care obligations, piece-rate work that must still reach minimum wage per hour, and Holidays Act entitlements for people whose hours change every week.
BambooHR and Workday were designed for a salaried office where headcount moves by ones and twos. Yours moves by hundreds, twice a year, and a large part of it arrives from Vanuatu, Samoa or Tonga under the Recognised Seasonal Employer scheme with obligations attached: minimum guaranteed hours averaged across the agreement, accommodation and transport deductions that must be correct, and pastoral care records you may be asked to produce.
Gusto and ADP are not New Zealand payroll, and even the local products struggle at the edges that matter here. Piece rates for picking and thinning still have to meet the minimum wage for every hour worked, which means a top-up calculation someone has to run. The Holidays Act 2003 requires the greater of two calculations for a worker whose weekly hours swing between 20 and 55, and that arithmetic done in a spreadsheet is exactly how New Zealand employers end up with expensive remediation projects.
What HR costs in Hastings
| Project scope | Typical cost | Timeline |
|---|---|---|
| Seasonal workforce and onboarding module | NZ$55,000 to NZ$85,000 | 12 to 16 weeks |
| Full workforce platform with piece rates and RSE tracking | NZ$95,000 to NZ$150,000 | 18 to 26 weeks |
| Payroll integration and reconciliation layer only | NZ$22,000 to NZ$40,000 | 5 to 8 weeks |
The fix: HR built for Hastings, not rented
Keep a New Zealand payroll engine such as PayHero, Smartly or iPayroll for the actual pay run, PAYE, KiwiSaver and payday filing to Inland Revenue. Build the layer above it that those products do not cover: crew and gang structures, RSE agreement tracking, piece-rate capture with live top-up calculation, accommodation deduction management and competency records. That layer needs to read hours from the same place your field app records them, feed labour cost into your packhouse system, and share training records with your induction platform.
- Your workforce triples for a season and your current system was designed for permanent staff
- You use piece rates and the minimum wage top-up is being calculated by hand
- RSE obligations are tracked in spreadsheets separate from payroll
- Training and certification evidence takes hours to assemble for an audit
- You have a stable team under about 40 people on standard hours and a New Zealand payroll product covers you
- Your seasonal labour is supplied by a contractor who carries the employment obligations
- You need core payroll only, in which case buy it and do not build it

How long it takes, phase by phase
Exactly what you get
A workforce system that matches the shape of a Hawke's Bay season. Bulk onboarding that can process a coach load of new starters in a morning, crew structures that mirror your gangs, piece-rate capture that calculates top-ups daily, RSE agreement tracking with accommodation and transport deductions, and a competency register that produces audit evidence on demand.
Payroll stays with a New Zealand provider, integrated with a reconciliation report your payroll officer signs off before every run. You also get documented calculation logic, which matters more than it sounds: when someone questions a top-up or an entitlement in two years, you want a written specification rather than a developer's memory.
How to choose a developer in Hastings
Employment calculation is the one area where an inexperienced team will cost you real money. Ask what they know about the Holidays Act 2003, piece-rate obligations under the Minimum Wage Act, and RSE requirements. If the answers are vague, insist on an employment specialist being funded inside the project rather than hoping the developer picks it up.
Ask how the system behaves in the first week of a season, when several hundred people are being onboarded, inducted and put on the line at once. Then check the integrations: hours from your field capture app, labour cost into your reporting, and training records shared with your induction system.
- Piece-rate earnings and minimum wage top-ups calculated daily, so supervisors can act on a slow gang instead of paying for it later
- RSE obligations tracked in one place: visa expiry, guaranteed hours averaged across the agreement, accommodation charges and pastoral care contact
- Holidays Act calculations applied consistently to variable hours workers rather than approximated in a spreadsheet
- Competency and certification records available instantly for a customer audit or a WorkSafe visit
- Onboarding several hundred seasonal staff becomes a repeatable process rather than a fortnight of manual data entry
- Employment legislation changes, and your system needs an owner who watches for it rather than assuming the software knows
- Payroll calculation itself is a poor thing to build from scratch, so you accept a dependency on a payroll provider and its API
- Getting Holidays Act logic right takes real specialist input, which adds cost and time to discovery
- Seasonal staff turnover means training on the system is a recurring cost, not a one off
- !They have not heard of the Recognised Seasonal Employer scheme. Ask them to explain guaranteed hours averaging back to you
- !They propose building payroll itself. Ask why they would rebuild PAYE, KiwiSaver and payday filing that PayHero already does
- !Holidays Act is treated as a configuration setting. Ask how the greater-of calculation works for a worker on 20 hours one week and 55 the next
- !No reconciliation step before the pay run. Ask what report the payroll officer checks on a Monday morning in March
- !Onboarding is a form. Ask how 180 new starters are processed in the week before the season opens

Frequently asked questions
What does custom HR software cost for a Hastings packhouse?
A seasonal workforce and onboarding module typically costs NZ$55,000 to NZ$85,000 over 12 to 16 weeks. A full platform with piece-rate handling and RSE tracking runs NZ$95,000 to NZ$150,000. Digital Heroes usually builds onboarding and piece rates first, since those deliver value in the very next season.
Can it handle Holidays Act calculations for variable hours staff?
It can, and this is one of the main reasons Hawke's Bay employers commission a custom layer. The Holidays Act 2003 requires the greater of two calculations for holiday pay, which is straightforward for salaried staff and genuinely difficult for packhouse workers whose weekly hours swing widely. Fund specialist employment input during discovery and get the logic documented.
How does the system handle RSE crews?
It tracks each worker against their agreement: visa validity, guaranteed hours averaged over the period, accommodation and transport deductions, and pastoral care contact records. Keeping this beside actual worked hours means a shortfall in guaranteed hours is visible in week four rather than discovered at the end of the season.
Do we still need PayHero, Smartly or another payroll product?
Yes, and keep it. New Zealand payroll compliance covering PAYE, KiwiSaver, ESCT and payday filing to Inland Revenue is well solved by existing products, and rebuilding it is poor use of budget. The custom system feeds accurate hours, piece-rate earnings and top-ups into payroll and reconciles the result.
How are piece-rate minimum wage top-ups calculated?
The system compares each worker's piece-rate earnings against hours worked at the applicable minimum wage for each day and calculates the shortfall automatically. Doing this daily rather than at the end of the pay period lets supervisors address a struggling picker during the week, which is better for the worker and cheaper for you.
Can it manage inductions and certifications for seasonal staff?
Yes, with a competency register covering GrowSafe, forklift certification, machine sign-offs and food safety training, including expiry alerts. Pair it with an induction platform so a new starter completes required training on day one and the record is created automatically rather than being filed by hand.
How fast can we onboard several hundred people?
With bulk onboarding, document capture and a device based self service flow, a large intake can be processed in a morning rather than over a fortnight. The bottleneck usually becomes physical checks and inductions rather than data entry, which is the right place for the bottleneck to sit.
What about ACC levies and health and safety records?
The system holds the incident, near miss and hazard records that the Health and Safety at Work Act 2015 expects you to maintain, and classifies labour by activity so your ACC levy position is supportable. The levy calculation itself sits with ACC, but the underlying records need to be defensible and quick to produce.
Who owns the calculation logic if we change developers?
You do, along with the code, provided the contract transfers intellectual property on final payment. Insist on written calculation specifications for anything involving pay, because those documents are what protect you if an entitlement is challenged years after the developer has moved on.
What tech stack should custom HR software use?
Can we keep using BambooHR while the custom system is being built?
What should I prepare before contacting an agency about HR software?
Is Workday realistic for a company under 500 employees?
What does it cost to maintain custom HR software after launch?

Who can build custom HR software for a business in Hastings?
Digital Heroes builds custom HR software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Hastings gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other HR software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
