Holidays Act 2003 maths on shift and overtime workers is what will actually cost your Hutt Valley business money
Custom HR (Human Resources) software for a Lower Hutt employer runs NZ$50,000 to NZ$120,000 over 4 to 7 months, and the first thing to understand is what you should not build. Payroll itself belongs in a New Zealand product that handles Holidays Act 2003 calculations, payday filing to Inland Revenue, KiwiSaver and ACC levies, because those rules are unforgiving and change. Gusto does not operate in New Zealand at all, and BambooHR and Workday were designed around United States and global leave models that do not match relevant daily pay or average daily pay. What you build is everything around payroll: rostering, competency and ticket tracking, timesheets that reflect real shift patterns, and site-level health and safety records.
You employ welders, machinists, apprentices and installers. Some are salaried, some are waged, most work variable hours, and a few pick up overtime and weekend call-outs. Holidays Act 2003 requires leave to be paid at the greater of relevant daily pay or average daily pay, which is straightforward for a nine-to-five office and genuinely hard for a Seaview shop where last week was 52 hours and this week was 31. Get it wrong for a few years across thirty staff and the remediation bill is the kind of number that ruins a good year.
The imported HR platforms do not help, because they model leave as an annual balance of days. New Zealand law does not work that way, and a system that quietly assumes it will produce numbers that look tidy and are wrong. Meanwhile the things that actually matter to a Hutt Valley employer, such as which welder holds a current ticket for a procedure, whether an apprentice's hours are being recorded for their qualification, and who has a current site induction, live in a spreadsheet and a folder.
Where the off-the-shelf tools fall short
- Leave entitlement and payment for variable-hours staff is calculated manually, and nobody is confident it is right
- Welding tickets, electrical registrations, forklift and first aid certificates expire without warning until someone notices on site
- Apprentice hours and unit standard progress are tracked on paper, so training records are incomplete when the industry body asks
- Timesheets are entered twice, once for job costing and once for payroll, and the two versions never match
Custom HR: what Lower Hutt teams actually get
Build the operational HR layer and keep a New Zealand payroll product underneath it. A custom system for a Lower Hutt employer holds rosters that reflect real shift patterns, one timesheet that feeds both job costing and payroll so nothing is entered twice, competency records with expiry alerts for tickets and registrations, apprentice hour and unit standard tracking, and site induction and health and safety records tied to people and locations. It exports cleanly to payroll for the Holidays Act calculation rather than attempting that calculation itself, which keeps you compliant without owning the hardest legal maths in New Zealand employment.
Feature priorities for Lower Hutt teams
Lower Hutt HR: the full scope
Everything an HR build here can cover: applicant tracking system (ATS), BambooHR alternative, Workday integration, leave management, performance management software, custom HR software and HRIS development.
- You employ variable-hours and shift staff and current leave handling is manual and uncertain
- Certification and ticket expiry is tracked on a spreadsheet and has already caused a problem on site
- Timesheets are entered twice and job costing and payroll disagree
- You run apprentices and cannot produce complete training records on request
- Your team is mostly salaried office staff on regular hours
- You have fewer than about twenty-five employees and a payroll product plus a spreadsheet still works
- A New Zealand product such as PayHero or Smartly already covers your rostering and timesheet needs
- You have no internal HR owner, which matters more for adoption than the software does
The honest cost picture for Lower Hutt
| Project scope | Typical cost | Timeline |
|---|---|---|
| Timesheets, rostering and competency register | NZ$50k to NZ$75k | 4 to 5 months |
| Adds apprentice tracking and health and safety records | NZ$80k to NZ$100k | 5 to 6 months |
| Multi-site build with self-service portal and payroll integration | NZ$100k to NZ$120k | 6 to 7 months |
Timeline: what happens, and when
Exactly what you get
The operational half of HR, built properly, with payroll left to a New Zealand product. Concretely: rosters aware of who is qualified for what; one timesheet feeding job cost and payroll; a competency register that warns you before a welding ticket or electrical registration expires; apprentice hours and unit standards recorded as they happen; leave requests that export clean data for the Holidays Act calculation; and health and safety records tied to person and site. You get source code, documentation and a tested payroll export. Timesheets are the shared spine here, so this connects directly to ERP (Enterprise Resource Planning) software for job costing, to field service management software for crews, to LMS (Learning Management System) development for training delivery, and into business intelligence (BI) dashboards for labour utilisation.
How to choose a developer in Lower Hutt
The most useful filter is whether they push back on building payroll. A supplier who volunteers to write your Holidays Act calculation either does not understand the risk or is happy for you to carry it, and both are disqualifying. Ask which New Zealand payroll products they have integrated with and what the export format looked like. Ask how they would model a call-out at 2am on a Sunday, because that single question separates people who have built for trades from people who have built for offices. Confirm Privacy Act 2020 handling in the design, including who can see what and whether access is logged, and insist on a pilot with one crew before rolling timesheets out across the business.
- One timesheet feeding both job cost and payroll, which removes double entry and the reconciliation that follows it
- Expiry alerts on welding tickets, electrical registrations and site inductions before someone turns up unqualified
- Apprentice hours and unit standard progress recorded as they happen, so training body reporting is a report rather than a project
- Rosters that model real shift patterns, overtime and call-out rather than a nine-to-five assumption
- Health and safety records tied to person, site and date, which is the evidence you need under the Health and Safety at Work Act 2015
- You are still dependent on a payroll vendor for Holidays Act and IRD compliance, so this is an addition rather than a replacement
- Employment law changes, and your system needs a maintenance budget to keep pace with them
- HR data is sensitive under the Privacy Act 2020, which raises the security and access control bar for the whole build
- Staff adoption of digital timesheets is a genuine change management effort, particularly with long-serving trades staff
- !They offer to build payroll. Ask how they intend to keep Holidays Act and IRD payday filing current, then reconsider
- !No questions about shift patterns or overtime. Ask how their design handles a 52-hour week followed by a 31-hour week
- !Privacy is not mentioned. Ask who can see salary and disciplinary data and how access is logged
- !Certification tracking is a date field. Ask what happens thirty days before a welding ticket expires
- !No payroll integration plan. Ask specifically which New Zealand payroll products they have exported to before

Frequently asked questions
What does custom HR software cost for a Lower Hutt manufacturer?
NZ$50,000 to NZ$75,000 for timesheets, rostering and a competency register, delivered in 4 to 5 months. Adding apprentice tracking and health and safety records takes it to NZ$80,000 to NZ$100,000. This excludes payroll itself, which should stay with a New Zealand payroll product rather than being built.
Should we build payroll to handle Holidays Act calculations ourselves?
No. The Holidays Act 2003 requires paying leave at the greater of relevant daily pay or average daily pay, and the rules around variable hours, public holidays and termination are where employers get caught. New Zealand payroll vendors maintain that logic and update it as interpretation changes, which is a liability you should let them carry.
Why do BambooHR and Workday not fit a New Zealand employer well?
Both model leave as an annual balance of days, which does not reflect how New Zealand entitlement and payment actually work for variable-hours staff. They also do not handle payday filing to Inland Revenue, KiwiSaver or ACC levies natively. Gusto is worth mentioning only to rule out, since it does not operate in New Zealand.
Can the system track welding tickets and electrical registrations?
Yes, and it is one of the highest-value features for a Hutt Valley employer. A competency register holds each qualification, its expiry, the evidence document and the work it authorises, then alerts the supervisor and the individual well before expiry. It also lets rostering refuse to assign someone to work they are not currently qualified for.
How do we handle apprentice hours and unit standard reporting?
Log hours against the work type as they happen through the same timesheet, and map them to the unit standards your industry training arrangement requires. Reporting then becomes a query rather than an evening spent reconstructing a year from job sheets. Confirm the exact evidence format your training body expects during discovery, because it varies by trade.
What are our Privacy Act 2020 obligations for HR data?
You must hold personal information securely, use it only for the purpose it was collected, and be able to provide an individual access to their own information on request. Practically that means role-based access, encryption, audit logging of who viewed what, and a defined retention period. Build the access model in from the start, because bolting it on later is expensive.
Will our trades staff actually fill in digital timesheets?
They will if it takes under a minute and works with dirty hands on a shop-floor terminal or a phone. They will not if it requires a laptop and a login they forget. Pilot with the crew most likely to object, and treat their complaints as design requirements rather than resistance.
Can we integrate with PayHero, Smartly or MYOB payroll?
Yes, and integration with New Zealand payroll products is a standard part of these builds. The usual pattern is an approved timesheet export in the vendor's expected format, plus employee record synchronisation so new starters are not created twice. Confirm the specific product before design, because export formats differ meaningfully.
How long before we see a return on this build?
Most Lower Hutt employers see the double-entry saving immediately and the compliance benefit within the first certification cycle. The larger return arrives when accurate labour hours start feeding job costing, because that changes what you quote. Digital Heroes recommends measuring hours spent on timesheet reconciliation before the build so the comparison afterwards is real.
Can we migrate years of data out of our current system into new custom software?
Is Workday realistic for a company under 500 employees?
Can custom software replace ADP Workforce Now?
Are local developer rates in Lower Hutt worth it compared to hiring an offshore team?
How long does it take to build a custom web or mobile app from scratch?
How do I vet a software development agency before signing a contract?
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Can we keep using BambooHR while the custom system is being built?
Who can build custom HR software for a business in Lower Hutt?
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 Lower Hutt 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.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh.

Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
