The best line trimmer in NZ overall is the Stanley FatMax V20 18V Line Trimmer Kit, which arrives complete with a 2.0Ah battery and charger, runs an automatic line feed and weighs 3.2kg fully assembled. That makes it the easiest option for a New Zealand garden where the trimmer comes out for twenty minutes at a time, rather than a bare tool that assumes the right battery is already in the shed.
Cordless line trimmers, also called whipper snippers, string trimmers or weed eaters, have become the standard for NZ lawns, trading a bit of raw power for lighter weight, less noise and none of the fuel mixing that comes with a petrol trimmer.
We could not find a genuine petrol-powered trimmer that ships to New Zealand at a sensible price. The first four picks below are named-brand cordless trimmers from Bosch, Stanley and TOPEX. The remaining four are budget marketplace tools without an identifiable brand, so we have flagged those clearly as unverified against any manufacturer page, rather than presenting them with the same confidence as the branded options. If you’re tidying up the rest of the section too, our guides to the best leaf blowers and best hedge trimmers cover the other side of the job.

1. Stanley FatMax V20 18V 2.0Ah Line Trimmer Kit – Best Complete Kit
This kit comes with everything included, the trimmer, a 2.0Ah battery and a charger, so there is nothing extra to buy before you can start trimming.
It runs on Stanley’s V20 battery platform, uses an automatic line feed, and weighs 3.2kg fully assembled.
It suits homeowners with small to medium yards who want a straightforward, ready-to-go option rather than piecing together a bare tool and a separate battery.
Pros
- Complete kit with battery and charger included
- Automatic line feed, no manual bumping required
- Backed by Stanley’s V20 battery platform
Cons
- Heavier than the Bosch bare tool at 3.2kg
- Cutting width isn’t clearly published by the retailer
Key specs: 18V (V20 platform), includes 2.0Ah battery and charger, automatic line feed, 3.2kg.
2. Bosch EasyGrassCut 18 (Bare Tool) – Best for Bosch Owners
Bosch’s EasyGrassCut 18 runs on the brand’s 18V Power For All battery platform, the same batteries used across Bosch’s home and garden tools, so it is worth a look if you already own one.
It uses a semi-automatic spool that feeds fresh line every time you release the trigger, plus a twist-and-edge function for tidying garden bed edges, and Bosch says a full charge can trim the edges of roughly six tennis courts.
It is sold as a bare tool, so you will need to already own or separately buy a compatible 18V battery and charger.
Pros
- Runs on Bosch’s wide 18V Power For All battery range
- Semi-automatic line feed with a dedicated edging function
- Lightweight at around 2.2kg
Cons
- Battery and charger sold separately
- 26cm cutting width suits smaller lawns, not overgrown sections
Key specs: 18V, 26cm cutting width, semi-automatic spool, bare tool (battery and charger not included).
3. Bosch EasyGrassCut 18 with Battery & Charger – Best Complete Bosch Kit
This is the same EasyGrassCut 18 trimmer as the bare tool above, but bundled with a 2.5Ah battery and a fast charger, so there is nothing extra to buy.
It shares the same semi-automatic spool, twist-and-edge function and 26cm cutting width as the skin-only version, just with the battery platform included.
It is the simplest way into the Bosch 18V ecosystem if you do not already own a compatible battery, and the same battery will run other Bosch 18V garden and home tools later.
Pros
- Ready to use straight away with battery and charger included
- Same semi-automatic spool and edging function as the bare tool
- Battery works across Bosch’s wider 18V tool range
Cons
- Costs more than buying the bare tool if you already own a battery
- Still a 26cm cutting width, better for smaller lawns
Key specs: 18V, 26cm cutting width, includes 2.5Ah battery and fast charger, semi-automatic spool.
4. TOPEX 20V Cordless Lawn Grass Line Trimmer, 2-in-1 – Best Budget / 2-in-1
TOPEX’s 230mm trimmer runs on a blade-based cutting system rather than a traditional string spool, and includes a flower guard to help protect garden beds and ornaments while edging.
It converts between trimmer and edger modes, comes with a 20V 1.5Ah battery and charger included, and weighs about 2kg.
Reviewers give it 4.0 out of 5 stars on average, praising the light weight and ease of use, though a couple of reviews mention the edger-mode conversion instructions could be clearer.
Pros
- Includes battery and charger at a budget price
- Lightweight at around 2kg with a 2-in-1 trimmer and edger design
- Flower guard helps protect plants and garden ornaments
Cons
- Blade-based cutting system rather than a traditional string line
- One reported case of a battery arriving faulty
Key specs: 20V, 230mm cutting width, blade-based cutting system, includes 1.5Ah battery and charger, 2kg.
5. Cordless 3-in-1 Weed Wacker with Wheels – Best for Edging & Multi-Function
This is a generic marketplace trimmer rather than a named brand, so we could not independently verify it against a manufacturer’s own page, but the listing itself is detailed enough to include here as a budget multi-function option.
It runs a 650W motor at up to 8,300 RPM from two included 21V 2000mAh batteries, and doubles as a wheeled mini-mower and edger alongside its trimming function.
It suits anyone wanting one tool that can trim, edge and tidy small patches of lawn without buying three separate machines, though build quality on generic tools like this can vary between batches.
Pros
- Three functions in one tool: trimmer, edger and wheeled mini-mower
- Comes with two batteries included
- Budget price for the feature set
Cons
- Generic marketplace brand with no independent reviews or manufacturer page to verify against
- Build quality and after-sales support can be inconsistent on unbranded tools
Key specs: 21V, 650W motor, up to 8,300 RPM, includes 2x 2000mAh batteries, wheeled 3-in-1 trimmer/edger/mini-mower.
6. Compact Cordless Garden Trimmer & Hedge Cutter – Best Ultra-Compact
This is another generic marketplace tool without an identifiable brand, so treat it as a budget option we could not independently verify rather than a name you would recognise at a hardware store.
It is a compact, lightweight cordless trimmer and hedge cutter with a small 10cm cutting width, built around a 1300mAh battery and a contoured handle.
It suits tight spaces like balconies, small courtyards and light hedge shaping rather than an actual lawn, given how narrow its cutting width is.
Pros
- Very lightweight and compact for tight spaces
- Simple, comfortable grip for short trimming jobs
- Budget price point
Cons
- Generic marketplace brand with no independent reviews or manufacturer page to verify against
- 10cm cutting width is too narrow for anything beyond very light trimming
Key specs: Cordless, 10cm cutting width, 1300mAh battery, compact hedge and grass trimmer combo.
7. Electric Weed Wacker, Height-Adjustable Brush Cutter – Best for Thick Weeds
Another generic marketplace pick, this one swaps between interchangeable metal, saw and plastic blades depending on what you are cutting, from thick weeds to light branches to tender grass.
It is lightweight at 2.9kg, with an adjustable shaft length and a head that tilts from 0 to 90 degrees, plus a safety lock button on the trigger.
It is aimed at rougher, overgrown patches rather than a manicured lawn, given the emphasis on cutting through thick weeds and small branches.
Pros
- Interchangeable blades for weeds, branches and grass
- Adjustable shaft length and tilting head for different jobs
- Lightweight at 2.9kg
Cons
- Generic marketplace brand with no independent reviews or manufacturer page to verify against
- Better suited to rough, overgrown areas than a tidy lawn edge
Key specs: Cordless, interchangeable metal, saw and plastic blades, adjustable length 34.6 to 47.2 inches, 0-90° head angle, 2.9kg.
8. Battery Strimmer with Telescopic Pole – Best Accessory Bundle
This generic kit bundles the most accessories of any trimmer here: two batteries, two steel blades, five nylon blades, a 15cm saw blade, two glide wheels, safety goggles and gloves.
Its telescopic pole extends to 127cm for reaching under bushes or trimming on slopes, then folds down to 50.5cm for storage.
As with the other generic picks in this guide, there is no independent brand page to check the claims against, so treat the extensive accessory list as a convenience rather than a guarantee of quality.
Pros
- Extensive accessory bundle: multiple blade types, wheels, goggles and gloves included
- 127cm telescopic pole reaches under bushes and on slopes
- Folds down to 50.5cm for compact storage
Cons
- Generic marketplace brand with no independent reviews or manufacturer page to verify against
- Most expensive pick in this guide despite being an unverified brand
Key specs: Cordless, 2x batteries, 127cm telescopic pole (folds to 50.5cm), 2x steel blades, 5x nylon blades, 1x saw blade.
How to Choose the Best Line Trimmer for You
The right line trimmer comes down to matching the power source and cutting width to the size of your section.
Cordless vs corded vs petrol
Cordless battery trimmers now cover most home gardens without the fumes, pull-cords or extension leads of petrol and corded options, though petrol still wins for very large or overgrown properties.
Cutting width
A narrower 10cm to 26cm cutting width suits small courtyards, balconies and edging, while anything over 30cm covers ground faster on a bigger lawn.
Bare tool vs kit
If you already own batteries from the same brand’s other tools, a bare tool saves money. Otherwise, a complete kit with a battery and charger included is the simpler buy.
Named brand vs generic
A named brand like Bosch, Stanley or TOPEX gives you a manufacturer page, spare parts and a track record to check reviews against. Generic marketplace trimmers can be cheaper and sometimes bundle more accessories, but quality and after-sales support vary more between individual units.
For the rest of the yard, the guide to lawn mowers is worth a look.
Verdict
For most New Zealand gardens, the Stanley FatMax V20 Kit is the easiest choice since it is ready to use straight away. Bosch owners with a spare 18V battery should go with the bare EasyGrassCut 18, or the bundled version if starting from scratch, and budget shoppers who don’t mind a blade-based cutting system will do well with the TOPEX 2-in-1. The four generic picks are worth a look if you want extra functions or accessories for less, but go in with realistic expectations on build quality and support.
Frequently Asked Questions
Is a cordless line trimmer powerful enough for a normal NZ lawn?
Yes, an 18V to 20V cordless trimmer is more than enough for typical suburban lawns and edging. Only very large, overgrown sections really call for a petrol trimmer.
What’s the difference between a line trimmer and a brushcutter?
A line trimmer uses lightweight nylon line, or in some budget models small blades, for grass and light weeds, while a brushcutter uses a rigid metal blade to cut through thicker scrub and saplings.
Do I need a separate battery and charger?
It depends on the model. Some trimmers, like the Stanley FatMax kit or the bundled Bosch EasyGrassCut here, include a battery and charger, while bare ‘skin only’ tools rely on you already owning a compatible battery from the same brand.
How long does a charge last?
Runtime varies by battery size, but most 18V to 20V trimmers with a mid-size battery will comfortably cover an average suburban lawn’s edges and trims on a single charge.
Can I use a line trimmer to edge garden beds?
Many modern trimmers, including a couple of the ones in this guide, include a dedicated edging mode or a flower guard specifically for tidying garden bed borders without a separate edging tool.
Are the generic, unbranded trimmers in this guide safe to buy?
They can be a reasonable budget option, but since there’s no manufacturer page or independent review history to check them against, it’s worth reading the actual buyer reviews and photos on the Amazon listing itself before purchasing, and keeping expectations modest on build quality and after-sales support.
