How to Start a Lawn Mowing Business in NZ, and Why Winter Decides Whether It Lasts

Servy Team8 October 202611 min read

Starting a lawn mowing business in New Zealand is cheap and quick. As a sole trader you need your IRD number, a commercial mower, a trimmer and blower, a way to move them, and public liability insurance. There's no licence for mowing lawns, and GST registration only becomes compulsory once you turn over $60,000 in 12 months. You could be mowing paid lawns next week.

The hard part comes later. The same 40 customers who keep you flat out in November need you about a third as often in July. The guides that rank for this search, such as Sprintlaw's legal checklist and Husqvarna's equipment list, cover structure, contracts and gear well. None of them puts numbers on the seasons, on ACC, or on the tip fees. Below, we do that with Auckland figures.

We're Servy, an Auckland booking app for lawn and garden providers, cleaners and movers. Where this guide talks about Servy, the terms come from our lawn and garden provider FAQ, and everything else is linked to its source so you can check it.

The setup list, briefly

Mower. A commercial walk-behind is the core purchase. Honda's HRU216M3, a common contractor mower, lists at $2,499 including GST at one NZ dealer. Anything you buy for the business that costs over $1,000 has to be depreciated over several years for tax. Items of $1,000 or less can be deducted in full in the year you buy them, which covers most trimmers, blowers and hand tools.

Trimmer, blower, edger and catcher bags. Servy expects providers to arrive with all of it. The FAQ lists "a mower, edger, line trimmer, blower, and any other tools required", and customers aren't asked to supply anything.

A way to carry it. A trailer or ute. Check your motor insurance before you tow a paid job anywhere (more on this below).

Public liability insurance. Not a legal requirement, but Servy requires it before your first job, and most customers will assume you have it.

An IRD number and a separate bank account. Your personal IRD number is your business tax number. Every dollar you earn goes on an IR3 return after 31 March.

What a round earns, season by season

Auckland lawn price guides cluster around the same per-visit numbers. EvergreenGroup's Auckland guide puts a medium lawn at $45 to $65 a visit, and gives this mowing calendar: every 1 to 2 weeks in summer (December to February), every 2 to 3 weeks in spring and autumn, and once a month or as needed in winter.

Put a round of 40 regular customers through that calendar at $55 a mow and each part of the year looks like this. These are our calculations from those published figures, using the middle of each frequency range:

Season	How often each lawn is mown	Mows per week	Takings per week
Summer (Dec–Feb)	About every 1.5 weeks	27	$1,467
Spring and autumn	About every 2.5 weeks	16	$880
Winter (Jun–Aug)	About every 4.3 weeks	9	$508

Across the year that's about 22 mows per customer and $48,500 in takings, before any costs. The annual figure looks fine. The winter figure is the one to plan for: a week that pays $1,467 in January pays about a third of that in July, while the van payments, phone bill and rent don't change.

You also can't solve winter by signing up more summer customers, because you size the round to the busiest weeks. If 27 mows a week is about what you can handle at the peak, 40 customers is roughly your limit, and in July you're working at around a third of your capacity.

When Auckland grass grows fastest

The calendars in pricing guides say summer is the busy season. The one set of measured grass growth figures we found from inside the Auckland region tells a slightly different story. DairyNZ's average pasture growth data includes Tomarata, near Wellsford, measured from 2010 to 2014. Growth there peaked in October at 45 kg of dry matter per hectare per day. It fell to 19 in July, but February was barely higher at 21.

Farm pasture isn't a suburban lawn, and a watered kikuyu lawn in Remuera will behave differently from a dry paddock, so treat this as a direction rather than a forecast. The direction is useful, though. The real rush is the spring flush in October and November, a dry late summer can quieten things down just when you expected to be busiest, and grass in Auckland doesn't stop growing in winter. Across June to August, Tomarata averaged a little over half its October rate.

The costs setup guides leave out

ACC costs more than you might expect. Lawn mowing sits in ACC classification unit 95250, gardening and turf management services. For 2026/27, that's a work levy of $1.76 per $100 of liable earnings, plus the $0.08 Working Safer levy and the $1.52 earners' levy, all plus GST (ACC Levy Guidebook 2026/27). That's $3.36 per $100 of profit, against $2.60 for a house cleaner. The work levy alone is about 2.6 times the $0.67 median across ACC's classification units. ACC also invoices self-employed people after their tax return is filed, so the bill for your first year arrives in your second. Our guide to starting a cleaning business walks through how that stacks up with provisional tax.

Tip fees. If you take clippings away, you pay to drop them off. At WM's Auckland transfer stations, a green waste load of up to 30 kg costs $21 at Papakura, $24 at East Tamaki and $28 at North Shore. Up to 100 kg costs $38 to $42. One tip run a day for a few combined lawns is affordable. One run per lawn eats most of the margin on a $55 job. The loads also have to be 100% garden waste, with no flax, bamboo or branches over 100 mm across, or they're charged at the general waste rate.

Vehicle costs. Inland Revenue's kilometre rate for 2025/26 is $1.20 a kilometre for a petrol vehicle and $1.30 for diesel, for the first 14,000 km a year. That rate covers fuel, maintenance, insurance, registration and depreciation together. Twenty kilometres of driving between scattered lawns costs about $24 at that rate, nearly half a mow. A round where your customers sit in two or three neighbouring suburbs is worth more than the same number of customers spread across the city.

Two insurance gaps worth checking

Your car policy and the trailer. Private motor policies can exclude business use that you might assume is covered. One NZ example, Initio's motor vehicle policy, says there is no cover while the vehicle is used for a servicing business doing maintenance at homes, or "to tow for financial gain or reward". Policies differ, so read your own, but if you tow a mower trailer to paid jobs on a private policy you may not be covered when something goes wrong. Tell your insurer what you use the vehicle for.

Your liability policy and the lawn itself. Public liability policies usually exclude damage to the property you're working on. For example, the DUAL general liability wording sold through BizCover excludes "property on which the Insured is or has been working" and the cost of fixing defective work. A stone flung through a neighbour's window is the kind of claim liability insurance is for. Scalping a customer's lawn or cutting through their irrigation line may well come out of your own pocket. Ask your broker what the policy covers for each, and photograph the lawn before you start.

Five problems a lawn round runs into

A new round tends to hit the same five problems, often several at once.

Unpaid quoting. You can't price a lawn you haven't seen, so you either drive round to look at it for nothing or guess and then argue about it on the day.
Price pressure. On Facebook groups and bidding apps, someone with a cheaper mower and no insurance is always willing to do the job for $10 less.
Weather. A week of rain stacks up the lawns, and moving a booking around can annoy customers who can't see why you didn't come.
No-shows and late cancellations. You turn up, the gate is locked and the dog is out. That's a slot and a trip gone.
Winter. As the table above shows, your work drops to about a third.

How you find your customers decides how many of these you carry yourself. Our guide to finding odd jobs in Auckland compares Facebook, Airtasker, Builderscrack and Servy on fees, bidding and cancellations side by side. In brief: Facebook costs nothing but leaves every problem with you, Airtasker charges new Taskers 20% and makes you bid for each job, and Builderscrack charges for leads you may not win.

How Servy answers each one

Servy was built for this kind of work. From the lawn and garden provider FAQ:

No quoting. Jobs are priced from the property size the customer gives and the services they choose, such as mow only, or mow, edge and weed. Servy sets the price structure. You see the location, scope and price before you accept, so you never drive anywhere to quote.

No bidding. The customer sees a fixed price before they book, so there's nobody undercutting you on the job.

Weather. If conditions make a job dangerous or would leave a poor result, such as mowing a waterlogged lawn, you can arrange a new time through the app, and Servy's support team can help without it counting against your reliability rating.

Cancellations. If a customer cancels within 24 hours or isn't available when you arrive, they're charged a fee equal to one hour of your rate, and part of it is passed on to you.

Pay. The customer pays in the app. You keep 95% of each booking and all of any tip, and payouts reach your bank account through Stripe, usually two to five business days after the job.

Two things in the FAQ's growth tips are worth taking seriously for the winter problem. Sell regular fortnightly mowing to every customer whose first job went well, because regulars are what keep the round full. And sell seasonal work, such as spring clean-ups, autumn leaf removal and pre-summer tidies, to customers who already trust you. Servy's lawn and garden category covers mowing, edging, weeding and general tidying. It doesn't include tree removal, landscaping, irrigation or chemical spraying, which also keeps you out of work that needs separate qualifications or insurance.

If you have a trailer and take green waste away, say so on your profile. The FAQ notes that customers will pay more for it, and it's a simple way to stand out.

What Servy asks of you

You need to pass an identity and background check and hold New Zealand public liability insurance before your first job. You can apply while you arrange the insurance. Those requirements are why a homeowner is happy to let a stranger into their back garden, and why you don't have to win the customer over on the doorstep.

Servy is newer and smaller than Airtasker, and it won't fill every hour of a new round straight away. But you keep more of every job you get through it, and the ratings you earn stay on your profile and move you up the list customers see.

Where to start

Apply to Servy first. The background check takes a few days, so start it while you're buying gear.
Sort the insurance properly. Get public liability cover, and tell your motor insurer you'll be towing for paid work.
Buy a commercial mower, not a cheap one. A breakdown mid-job costs you a rating, and a domestic mower isn't built to run every working day.
Build your round in a tight area. Accept jobs in neighbouring suburbs so you spend your day mowing, not driving.
Set aside money from your first job. Put aside part of every payout for tax and ACC, and keep some for July, when you'll be mowing about a third as often.
