Most NZ tradies live job to job — finish one, hustle for the next. It's exhausting, and it means your income bounces around with the seasons. Maintenance contracts flip that model. Instead of chasing new work every week, you bill existing clients a fixed monthly or quarterly amount to keep their property, equipment, or systems running.
In 2026, as the construction market slowly recovers but project work remains lumpy and competitive, building a base of recurring service revenue could be the most reliable thing you do for your business this year.
What Is a Maintenance Contract?
A maintenance contract (also called a service agreement or preventative maintenance plan) is an ongoing agreement between you and a client where you provide regular inspections, servicing, or minor repairs for a fixed fee.
Examples by trade:
- Electrician: Annual switchboard check, smoke alarm testing, emergency lighting compliance inspections for commercial buildings
- Plumber: Quarterly hot water cylinder check, backflow preventer testing, drain jetting for restaurants or strata buildings
- HVAC/Heat pump technician: Bi-annual filter clean, refrigerant check, pre-summer/pre-winter service
- Builder/carpenter: Bi-annual exterior checks — gutters, cladding, joinery seals, deck inspections
- Painter: Annual touch-up and condition report for commercial or rental property landlords
- Roofer: Annual roof inspection and minor maintenance for commercial buildings
The work is usually not glamorous, but it is predictable — and that's exactly what a small business needs.
Why 2026 Is the Right Time to Start
New Zealand's construction sector is in recovery mode. Consent numbers are rising — Stats NZ recorded a 22.9% increase in new dwelling consents in February 2026 — but project pipelines remain patchy for many individual operators. Bigger contractors are winning the larger jobs, while smaller operators are competing hard for residential and light commercial work.
Meanwhile, your existing clients are sitting on years of deferred maintenance. Interest rates are easing, property owners are reinvesting, and landlords are under increased pressure from Healthy Homes standards and council compliance. This is exactly the environment where a well-priced maintenance plan sells itself.
How to Structure Your Maintenance Contract
A good maintenance agreement covers four things:
1. Scope of work — Be precise. List exactly what you will and won't do at each visit. "Check and clean heat pump filters" is better than "general service." Ambiguity is where disputes start.
2. Visit frequency — Quarterly, bi-annual, and annual schedules are the most common. Match the frequency to what the asset genuinely needs, not just what the client will pay for.
3. Pricing and payment terms — More on this below. Decide whether you're billing in advance or in arrears, and how often.
4. Callout rights — Decide whether contract clients get priority booking, a discounted call-out rate, or both. This is a key selling point.
Put everything in writing. You don't need a lawyer for a simple residential agreement — a clear one-page document with both signatures is enough. For commercial clients, have your solicitor or Tradie Law review it.
Pricing Models
There are two common approaches:
Flat Monthly Retainer
The client pays a fixed amount per month, regardless of how many visits fall in that month. You bill in advance, usually by direct debit.
Example: A restaurant owner pays $180 + GST per month for a bi-annual drain clean and quarterly grease trap inspection. That's $2,160 + GST per year — four visits at around $540 each.
This model is clean, predictable, and easy to administer. It works best when your visit frequency is regular and your labour is the main cost.
Per-Visit Invoice Under Agreement
The client commits to letting you do the scheduled work, but you invoice after each visit at the agreed rate. Less cash-flow-friendly for you, but easier for clients to accept.
Use our Hourly Rate Calculator to make sure your maintenance rate actually covers your costs, including travel time to recurring sites. And run the numbers through the Job Cost Calculator to confirm each visit is profitable after materials.
When pricing maintenance work, remember: you're not just pricing the labour hours on site. You're pricing reliability. Clients value having a trusted tradie who shows up on schedule without them having to chase quotes. That has real worth — price accordingly.
A common starting point: charge 10–15% less per visit than your standard call-out rate, offset by the certainty of repeat bookings and zero marketing cost for that revenue.
IRD Treatment of Prepaid Income
If you bill in advance — say, a full year's maintenance fee upfront — IRD treats that as income in the period it relates to, not necessarily when you receive the cash. Under accrual accounting, you recognise revenue as you perform the work.
However, many small tradies use cash accounting (income when received, expenses when paid). If you're on cash accounting and you receive a lump-sum annual fee, it's assessable income in the year you receive it, even if some of the work happens in the next tax year.
Talk to your accountant about which method suits you — especially if you're going to scale up your maintenance book significantly. MBIE and IRD both publish guidance on small business accounting methods. IRD's "Running a small business" section at ird.govt.nz is a useful starting point.

Selling Maintenance Plans to Existing Clients
Your warm base is the easiest place to start. After completing a job, send a follow-up message:
"We've just finished your bathroom renovation. A lot of our clients find it useful to have us back annually to check the waterproofing and grout seals — we can spot issues before they become expensive. We offer a simple annual check for $X. Want me to send through details?"
That's it. No hard sell. You're positioning it as a service, not a product.
For commercial and property management clients, frame the conversation around compliance risk. Healthy Homes deadlines, BWOF (Building Warrant of Fitness) requirements, and council compliance give them a business reason to say yes — not just a lifestyle one.
Managing Recurring Work
Once you have more than a handful of maintenance clients, ad-hoc scheduling breaks down fast. You need a system that reminds you when visits are due, logs what was done last time, and generates invoices automatically.
Fastcrew is designed for NZ tradies and handles recurring job scheduling well — you can set repeat jobs, attach client notes from prior visits, and manage the admin from your phone between other work. It beats a spreadsheet and a stack of reminder notes in your ute.
Getting Started: A Simple Action Plan
- List your top 10–15 existing clients who own property or equipment that needs regular attention.
- Work out what a sensible annual maintenance scope looks like for each, and what you'd charge.
- Draft a simple one-page service agreement (scope, frequency, price, payment terms).
- Contact three clients this week with a specific offer — not a general inquiry, a specific proposal.
- Set up recurring invoicing in your accounting software or app.
Start small. Even five or six maintenance clients generating $1,000–$2,000 each per year adds $5,000–$12,000 of near-guaranteed annual revenue to your base. That's the slow season covered before it starts.
