What Is the Best Heat Pump in NZ?
There’s no single “best” heat pump in New Zealand. Your Auckland villa has different needs than a Christchurch apartment or a farmhouse in Waikato. But certain brands do consistently rank higher than others. Here’s what actually matters when you’re shopping.
The Top Heat Pump Brands People Choose
Mitsubishi Electric
Mitsubishi Electric leads the pack. Canstar Blue has ranked them number one for customer satisfaction four years running, and they’ve won the top award eight times in the past nine years. Homeowners choose them for specific reasons: they’re genuinely quieter than competitors, they perform better in cold weather, and they last.
The quietest models start at just 18dBA on the lowest fan setting2 (for context, a whisper is around 20dBA). Standard heat pumps operate at 40dBA or higher. That’s the difference between barely hearing your heating system and being aware of it whenever you’re in the room.
Cold weather performance matters in New Zealand. Mitsubishi’s HyperCore range delivers its full rated heating capacity down to -15°C.3 Most heat pumps lose efficiency below 7°C. When winter temperatures drop to freezing, that guarantee means you actually get the warmth you paid for.
Daikin
Daikin sits firmly in second place. They won Canstar’s award in 2021 and earned five-star ratings for reliability and value for money. Their Cora series gets strong marks for quiet operation, and they’re often priced slightly below Mitsubishi. You sacrifice marginally on noise levels but gain on cost.
In fact, the Daikin US7 is the most energy-efficient split system heat pump currently available in New Zealand, with a 7-star “super efficiency” rating.
Panasonic
Panasonic is the underrated choice. Their energy efficiency ratings are excellent, the technology is solid, and pricing is competitive. There’s only one thing that holds them back: brand recognition. Panasonic heat pumps aren’t as popular as Mitsubishi or Daikin, so fewer installers have deep familiarity with their systems. Warranty support doesn’t feel quite as robust as a result.
The Panasonic Z35 Aero Series performs between -15°C and 24°C7 with the nanoeX feature designed to inhibit pollen and reduce odour from cooking and pets.
How to Actually Choose the Right One
Don’t obsess over the brand – rather, focus on picking a good installer and picking a unit that’s nicely sized to your space. An undersized, premium Mitsubishi is going to perform worse than a correctly sized Daikin. And if you hired an inexperienced installer who doesn’t know what they’re doing? Well, they’ll make any brand underperform no matter how much you pay.
What Actually Differs Between Brands
Noise Levels
Mitsubishi genuinely is quieter. Their quietest high wall models operate at 18dBA versus 40dBA or higher for standard competitors. In a bedroom, that difference is noticeable. A quiet heat pump lets you forget it’s running. A loud one becomes background irritation on cold nights.
Cold Weather Performance
If you’re in the South Island or mountains, this matters. Mitsubishi HyperCore guarantees full capacity down to -15°C. Some other brands see capacity drop as outdoor temperatures fall. In freezing conditions, that gap translates to actual comfort.
Energy Efficiency
Check the Coefficient of Performance (COP) and Energy Efficiency Ratio (EER) ratings. All modern inverter heat pumps from major brands are energy efficient. Some squeeze more heating or cooling per watt. The numbers vary more between specific models than between brands. For instance:
- Mitsubishi MSZ-LN25 HyperCore: COP 5.33 (heating)
- Daikin US7: 7-star super efficiency rating
- Panasonic Z35 Aero: Operates efficiently between -15°C and 24°C
Last but not least, the Energy Rating Label. New Zealand’s zoned rating system accounts for climate differences, so look at the rating for your specific zone.
Support and Availability
In rural areas, this becomes critical. You want parts and service available locally. Auckland? Less of an issue. Out of town? Ask locals what heat pumps they’ve installed and whether they can service them.

Frequently Asked Questions (FAQs)
Can I mix brands – like a Mitsubishi indoor unit with a Daikin outdoor unit – to get the best of both?
No. Heat pump systems are brand-specific. The indoor and outdoor units must be the same brand and model compatibility. Mixing brands will void warranties and the system won’t work properly. You have to commit to one brand for the full system.
Are Panasonic’s cheaper models worth considering if I’m on a tight budget?
Yes, if you can find a local installer who knows them well. Panasonic’s performance and efficiency are solid, and pricing is competitive. The main disadvantage is fewer installers have deep familiarity with their systems, so warranty support and service availability might be slower outside major centres. Check local installer availability before committing.
If a heat pump is properly sized and installed, would I really notice the difference between a Mitsubishi and a Daikin for everyday heating?
In most situations, no. Both heat and cool rooms effectively. You’d notice if Mitsubishi was quieter (especially if bedroom placement is relevant) or if you lived in a cold climate where HyperCore’s -15°C guarantee mattered. Otherwise, a correctly sized Daikin performs just as well for typical home heating needs at lower cost.
How important is installer familiarity with a brand – should I switch brands if my preferred installer doesn’t work with them?
Very important. A skilled installer who knows Daikin inside-out will outperform an inexperienced installer with a premium Mitsubishi. Varcoe works with both brands, so no matter what you end up choosing, we can have it installed for you.
The Honest Take
At Varcoe, we install all these brands. Mitsubishi customers are often slightly more satisfied with noise levels and cold weather performance. Daikin customers appreciate the value proposition. Panasonic users get reliable heating and cooling at a lower price point. Everyone stays warm in winter and cool in summer.
