Most major heat pump brands sold in New Zealand are well supported by trained local installers — but coverage can vary depending on your region, the brand's distribution network, and whether the unit was purchased through official NZ channels. Doing a quick check before you buy (or before you call someone out) can save you a lot of hassle down the track.
Why Brand Support Matters
A heat pump is only as good as the people who can install, service, and repair it. Even a high-quality unit can become a headache if:
- Spare parts aren't stocked locally and have to be shipped from overseas
- Warranty claims require an authorised service agent who isn't available in your area
- Firmware or fault codes are unfamiliar to local technicians
- The unit was a grey import — bought overseas and brought into NZ — which often voids the manufacturer's NZ warranty
How to Check If Your Brand Has Local Support
1. Look for an Official NZ Distributor
Start with the brand's website and look for a New Zealand-specific page, a local distributor, or a "find an installer" tool. Well-established brands in NZ — such as Mitsubishi Electric, Daikin, Fujitsu, Panasonic, and LG — all have dedicated NZ distributors and networks of trained installers and service agents.
If a brand's website only shows overseas contact details or prices in foreign currency, that's a red flag.
2. Ask the Installer Directly
A reputable heat pump installer will quickly tell you whether they're trained and authorised to work on a particular brand. Many installers are brand-authorised — meaning they've completed manufacturer training and can carry out warranty repairs. Ask:
- Are you authorised to install and service this brand?
- Can you access spare parts locally?
- Who handles warranty claims if something goes wrong?
You can find qualified local heat pump installers in your area through tradedirectory.co.nz.
3. Check the Warranty Terms Carefully
NZ warranty conditions vary between brands. Some offer 5–7 year warranties on parts and compressors, but only when installed by an authorised installer. If you use a non-authorised installer or purchase a grey import, you may find your warranty is significantly reduced or void entirely.
Under the Consumer Guarantees Act, you also have rights around goods being fit for purpose — but these rights are easier to enforce when you've bought through an official NZ retailer. Consumer NZ has useful guidance on your rights when buying appliances.
4. Search for Authorised Service Agents
Most reputable brands publish a list of authorised service agents on their NZ website. If you can't find any agents listed for your region (e.g., Northland, Southland, or the West Coast), that's worth knowing before you commit — especially for a rural property where a technician callout is already expensive.
5. Avoid Grey Imports
A grey import is a unit manufactured for another market (often Japan or Australia) and brought into NZ without going through the official NZ distributor. These units may:
- Have different voltage or frequency ratings
- Lack NZ-compliant documentation
- Not be covered by any NZ warranty
- Be unfamiliar to local technicians
Always ask your supplier or installer whether the unit is an official NZ-market product.
What About Less Common or Budget Brands?
There are a growing number of budget and lesser-known brands available through online marketplaces and some retailers. These aren't necessarily bad products, but you should do extra homework:
- Is there a NZ-based importer or distributor?
- Are spare parts available locally?
- Will your installer agree to work on it (and cover their workmanship)?
- Does it carry a recognised energy star rating?
For energy efficiency comparisons, Energywise provides guidance on choosing energy-efficient heating and cooling products for NZ homes.
Installation Is Restricted Work in NZ
It's important to know that heat pump installation involves restricted electrical and refrigerant work that must be carried out by a licensed professional. Specifically:
- Electrical connections must be done by a registered electrician (see EWRB)
- Handling refrigerants (such as R32 or R410A) requires a person with the appropriate refrigerant handling licence
A homeowner cannot legally do this work themselves. Always use a qualified, licensed installer.
Safety note: Incorrect installation can result in refrigerant leaks, electrical faults, fire risk, or reduced efficiency. Always verify your installer's credentials.
A Quick Brand-Support Checklist
| Check | What to Look For |
|---|---|
| Official NZ distributor | NZ website, NZ pricing, local contact |

When to Call a Professional
If you're unsure whether your existing heat pump brand is supported, or you're shopping for a new unit, talk to a qualified local installer before you buy. They can advise on which brands they're authorised to install and service in your area, and help you avoid a costly mismatch. Find a heat pump installer near you on tradedirectory.co.nz.
