A water blaster is a huge help in washing the outside of your house or your car thoroughly. If you’re looking for one, you’re in luck, as we’re listing the best water blasters in New Zealand today!
It can be difficult to make sure you buy the best water blaster, after all — particularly if you’re not quite sure what you should be looking for.
We’ve tried to make the task simpler by pre-selecting the best ones on the market. That way, you’ll be able to restrict your search to the highest-quality options from the start.
However, it still helps to know a little bit about how to choose the right water blaster for your needs. So, we’ll start with a quick review of what to consider, such as your purpose for the water blaster and the type you need.
After that, we’ll move on to the top water blasters in New Zealand.
Purpose of Cleaning
Before you buy a water blaster, you should first think about where you will use it. This will do a lot to narrow down your choices later on.
Are you going to use it to clean your walls, driveways, shed, patio, or deck? Or to do some heavy-duty jobs like construction space cleaning?
Then, you have to consider the frequency of your intended use. Are you going to clean daily, weekly, or twice or thrice a year?
List your answers to these questions so you can refer to them easily later on. Now, we’ll guide you through the different types of blasters available to make your choice even easier.
Types of Water Blasters
There are 4 main types of water blasters. These are cold, hot, electric, and gas-powered (such as diesel or petrol types).
In this article, we’ve included only the electric and gas-powered water blasters… for a simple reason. They just tend to be more useful all-around as well as more powerful.
Cold Water Blasters
Cold water blasters are the simplest types as they only use pressurised cold water. This will do for quick washing and cleaning for lighter duties around the house, but little else.
On the bright side, they’re fairly inexpensive options for water blasters. They can send out a strong gush of water, though still not one as powerful or effective as their gas-powered or electric counterparts.
Hot Water Blasters
A hot water blaster would be good for a lot of casual home cleaning projects. This is because it removes bacteria and mould present on the area you are cleaning.
It also packs enough pressure to take away relatively tough grime, oil or dirt. You do have to be careful with these, though, because the hot water makes them a bit dangerous.
Electric Water Blasters
These types of water blasters are convenient and easy to tow and carry around. They have a mid-range pressure level that makes them ideal for home, car, furniture, and floor cleaning.
However an electric water blaster is limited by the reach of its cord. It’s also safer not to use extension cords as they can negatively affect the performance of your water blaster.
This blaster’s advantage over gas-powered pressure washers is that they don’t emit any pungent smoke and produce less noise.
Petrol or Diesel Water Blasters
In terms of pressure washing, these water blasters are the most powerful options. This makes them perfect for use on larger-scale washdowns for offices, construction areas, or factories.
Because they don’t use an electric cord, they are not limited in reach and area either. However, they’re definitely among the heaviest and hardest-to-carry blasters!
Best Water Blasters in New Zealand
Now that you know the types of blasters available and how to orient your search for the best water blasters in New Zealand, let’s take a look at the top ones on the market:
1. Nilfisk 125 bar Compact Water Blaster with Hose Reel (C125)

The Nilfisk Water Blaster is apt for cleaning outdoor areas having moderate to tough dirt and stains. It is powered by a 1500W motor and has a powerful pressure of 125 bar.
That is plenty of punch and spray with a water flow rate between 5.2 to 7.3 litres per minute for a deep clean. Three nozzles come along with this set — tornado, lance and detergent.
Add to that its compact and lightweight form, you can move this around your backyard with ease. A cable holder and 6-metre hose make your washing smooth and untroubled.
The nozzles can be kept right in the body of this high pressure water blaster. The pump is also made from aluminium, which gives it resilience you can use for a long time!
Whether it’s your patio, car, furniture, garden, or retaining walls, the Nilfisk Water Blaster will do a remarkable job for a spotless and sparkling clean result!

Despite some minor complaints, customers mentioned that the water blaster made their house and property look clean and neat, thanks to its high-powered pressure.
Let’s check out James Starkey’s review:
“A great machine. I used a k2 karcher before and it doesnt come close to my new nilfisk. It goes together easy enough. I love the way it holds all its fittings in the rear so they are always to hand. I ended up searching for things to clean because its that good. Both cars and my works van are sparkling. The drive and rear garden slabs have come up like new. I would recomend this jetwash over the karcher in every area.”
Another customer, Steve Goacher even claimed it’s better than Karcher models:
“Powerful enough for all of my needs for washing the car, power washing the block paving and jobs in the garden. Comes complete with a good range of accessories. Excellent value for money and, in my opinion, far superior to the other make in yellow.”
2. Karcher Water Blaster Honda Petrol 3400PSI (G3400XH)
Best Petrol Water Blaster for Industrial and Commercial Projects
|Pump type||brass head axial cam|
|Maximum pressure||3400 psi|

For a heavy-duty and rugged water blasting, the Karcher Petrol Water Blaster G3400XH is an amazing choice! It uses the GC190 Honda engine, making it a cut above the rest!

What’s more, it includes stainless steel nozzles of 15, 25, 40 and detergent that can be attached easily. Its soap levels can also be adjusted to meet your requirements.
This water blaster’s versatile tyres make it easy to manoeuvre in different terrains. Its hose measures 7.6 metres, letting you maintain your distance when you jet wash.
For storage, you can place the gun sprayer back in its holder and fold down the handle neatly. The Karcher water blaster is simple and ergonomic to use, as you can see!
Be careful, though, as it might damage the wall or surface that you’re washing due to its raw, unflinching power. Leave it for the big and complicated jobs — that’s when it’ll come in handy!

- 3400 psi powered by Honda GC190 engine
- Perfect for industrial- and commercial-scale work
- Includes QuickConnect nozzles (15, 25, 40 and detergent)
- All-terrain tyres
- Easy to use and store
Two of the reviewers recommended this product because it’s both powerful and ergonomic. Due to this, you have to exercise caution everytime when using it.
One owner and tradesman andzie67 wrote his feedback:
“Huge difference from my older 2500psi machine. Gun feels very plastic and toy like, not sure how long it will last. The kickback is huge when opening the trigger of the gun, and lots of hand muscle is required to hold the trigger in the on position. Rips the dirt off the concrete so easily and only needs one pass of the wand, instead of 3 or 4 with the 2500 machine. Hose is heavy duty, 15m long but awkward to roll up. Still getting to know my machine, but so far it is amazing though could be too powerful for some of my jobs. I’m a 6ft,solid build landscape/gardening tradie and find the machine to be powerful and easy to use.”
3. Kärcher K4 Premium Electric Water Blaster (13241080)
Best Overall Water Blaster
|Pump type||Anti-rust N-Cor Pump|
|Maximum pressure||1900 psi|
|Flow rate||7 litres/minute|

You can adjust the pressure setting from soft to hard levels by just turning the nozzle clockwise. A trigger gun allows for easy spraying and washing on the surface it’s aimed at.

- 1900 psi for max pressure level
- Has detergent cleaner
- Two attachment nozzles (spray lance, pressure wash)
- Provides you with a 5-year warranty
The Kärcher K4 premium has mixed reviews. Some love it, but some feel they didn’t get the value they expected in terms of the spray holder, pressure level, and plastic parts.
But those who did like it felt it was worth the cost because it was so easy to use and consistent. One owner said this:
“Used to blast off several years of accumulated grime from our decking without any issues.
I’ve borrowed other peoples pressure washers before and always found them to be very temperamental, especially if using quite a long water hose. Maybe only because its new, but no such problems with this model.
The hose storage options arent great if Im honest, but I can live it as this will only get occasional use in the garden.
I’m hoping the water cooled motor will prolong its lifespan. Buying on “Prime Day” I got this for a great price, so happy days.”

Best in Favourable Reviews

Chris from Hokitika said:
“Really happy with the pressure and different nozzles on the machine. Perfect for cleaning the dirt and mud off my 4×4 and dirt bike, also used it in the house to get moss and dirt off. Really happy.”

“What makes it best over others :
- The price tag for 130bar pressure ( if compared to best brands like kaercher).
- Compact and durable
- Sufficient pressure for not only washing your car but cleaning anything like tile pathway and all areas where pressure washer is required.
The pressure is that much sufficient that it gives your car touchless washing, while using it , you can actually feel the pressure jerk in your arm.”
6. Jobmate Electric Water Blaster (GSH02A)
Best for Budget Water Blaster

As a final note, we’ll just remind you of some safety tips to apply to whatever water blaster you do decide to buy.
The first thing to note about water blasters is that they have a pressure level that breaks through wood or hard surfaces. In other words, they can be dangerous if you’re not careful with them.
Always be mindful of where you’re aiming your blaster. Try to avoid using it too if there are others in the vicinity who may cross your path.
Anyway, here are some more safety tips when using your water blaster:
- Before using a pressure washer, always keep an eye out for people, pets, objects, glass, or any unpredictability.
- Protect yourself at all times by wearing safety goggles, earmuffs, gloves and boots.
- Always turn it off when not in use.
- Never use an extension cord because it can decrease the performance of the water blaster.
- Be careful not to spray appliances, power outlets or cords. Steer clear of all forms of electricity.
- Don’t use ladders, instead work up your pressure washer to reach a certain height.
- Only use gas-powered water blasters outdoors and where there’s a good amount of ventilation.
- Above all, be safe and careful every time you use it.
And with this, we conclude our list of the best water blasters in New Zealand as of the moment! Any of the ones we’ve listed above should be capable of tackling most jobs.
