The best hot and cold therapy device in NZ overall is RENPHO’s Active+ Thermacool Massage Gun, which combines proper percussion massage with swappable heat and cold heads and holds a 4.8 out of 5 rating from 155 owners. If you want genuine cold therapy for a joint rather than a muscle group, KONGZEE’s Ice Machine for Knee is a completely different type of device built for exactly that, and if you’re on a budget, arboleaf’s massage gun brings the same heat-and-cold concept at a lower price.
We’ve compared six hot and cold therapy devices available in NZ, covering full-body massage guns, an eye massager, a hand massager, and a genuine joint cold-therapy machine, so you can match one to what you actually need relief for.
These are wellness and recovery devices, not medical equipment. They aren’t a substitute for professional medical advice, and anyone recovering from surgery, with a circulation condition, or with an open wound or skin condition should check with a doctor or physiotherapist before use.

1. RENPHO Active+ Thermacool Massage Gun – Best Overall
RENPHO’s Active+ Thermacool combines a proper percussion massage gun with a swappable head that adds two heat levels and two cooling levels, so you can switch between deep-tissue percussion, heat for loosening tight muscles, or cold for calming inflammation, all from one device.
It runs 5 speeds from 1800 to 2800 percussions per minute with a brushless motor rated at 55 decibels or quieter, and pairs over Bluetooth with the RENPHO Health App for guided routines. A 2000mAh battery gives around 2.5 hours of use per charge, and it ships with 5 interchangeable heads plus a travel case.
It’s also the best-reviewed device in this guide, rated 4.8 out of 5 across 155 reviews on RENPHO’s own site with a 98% recommend rate, and reviewers specifically confirm both the heat and cold settings work as advertised rather than being a gimmick.
Pros
- Combines percussion massage with heat and cold
- Excellent owner reviews (4.8/5, 98% recommend)
- App-guided routines via Bluetooth
- 5 interchangeable heads included
Cons
- Battery life (2.5 hours) is modest for a massage gun
- Pricier than RENPHO’s own simpler Thermacool model
Key specs: 5 speeds (1800-2800 ppm), 2 heat + 2 cold levels, 55dB, 2.5hr battery, 0.68kg.
2. RENPHO Thermacool Massage Gun Deep Tissue – Best Value Massage Gun
This is RENPHO’s simpler, more affordable Thermacool massage gun, running 5 speeds from 1800 to 3200 RPM with a quiet 40-decibel motor, and it ships with one heat/cold head plus four standard massage heads.
It charges quickly via 15W USB-C fast charging, reaching full charge in roughly 1.5 to 2 hours, and weighs just 1.5lbs, making it easy to hold for longer sessions. RENPHO’s own listed heat and cold temperatures for this model are inconsistent between its own regional sites and independent US retailers selling the same unit, so we can’t confidently state an exact degree figure here.
This appears to be an older, simplified version of the Active+ Thermacool above rather than a currently promoted flagship, and no independent review coverage was found for this exact model. If the temperature-accuracy question matters to you, the Active+ above has clearer, better-documented specs.
Pros
- More affordable than the Active+ Thermacool
- Fast USB-C charging (1.5-2 hours)
- Lightweight at 1.5lbs
- 5 interchangeable heads included
Cons
- Exact heat/cold temperatures aren’t consistently documented
- No independent reviews found for this specific model
- Appears to be a superseded, older model
Key specs: 5 speeds (1800-3200 RPM), heat/cold head + 4 standard heads, 40dB, USB-C charging.
3. RENPHO Eyeris 3 Eye Massager – Best for Eyes & Face
The Eyeris 3 takes RENPHO’s heat-and-cold approach to the eyes and temples specifically, combining voice control (it responds to 18 spoken commands after a “Hi Eyeris” wake phrase), 3 acupressure modes targeting 10 acupoints, and both a built-in heating element and a removable cooling gel mask.
It runs warm at 40 to 45°C, weighs just 348g without the gel pad, and charges via USB-C in 90 minutes for roughly 90 minutes of use, remembering your last-used settings for next time. It’s RENPHO’s most reviewed product in this guide by a wide margin, rated 4.7 out of 5 across 1,243 reviews with a 92% recommend rate.
Common themes in owner feedback are falling asleep faster and feeling genuinely refreshed after screen-heavy days, with several reviewers saying the design is presentable enough to leave out on a nightstand rather than hiding it in a drawer.
Pros
- Combines heat and a removable cooling gel mask
- Voice control with 18 recognised commands
- Excellent owner reviews (4.7/5, 1,243 reviews)
- Remembers your last-used settings
Cons
- Only suits eyes and temples, not a general-purpose device
- Cooling relies on a separate gel mask insert
Key specs: Heat 40-45°C, 3 acupressure modes, voice control, USB-C 90 min charge/90 min use, 348g.
4. arboleaf Massage Gun Deep Tissue with Heat and Cold – Best Budget Massage Gun
arboleaf’s massage gun brings the same heat-and-cold head concept to a more affordable price point, with a 60W brushless motor, 6 pressure-adaptive speed levels, and up to 35lb of stall force from a compact travel-friendly body.
An interchangeable heat/cold head joins 5 to 7 standard massage heads depending on the kit, and a 4000mAh battery gives up to 6 hours of use per charge, recharging via USB-C in around 3.5 hours. Independent reviews on Best Buy rate it 4.8 to 4.9 out of 5 across two listings, with reviewers calling the heat/cold head a “game changer” and praising its build quality and comfort.
One genuine drawback noted in those same reviews: the heated head can feel heavy and occasionally loosen on higher settings, so it’s worth checking it’s seated firmly before a session. It’s the most affordable way into a heat-and-cold massage gun in this guide.
Pros
- Most affordable heat-and-cold massage gun here
- Long battery life (up to 6 hours)
- Strong independent reviews (4.8-4.9/5 on Best Buy)
- Up to 35lb stall force, genuine deep-tissue power
Cons
- Heated head can feel heavy and loosen on high settings
- Fewer app/smart features than the RENPHO models
Key specs: 60W motor, 6 speeds, up to 35lb force, 4000mAh battery (up to 6hrs), ~55dB.
5. OUMIR Hand Massager for Arthritis – Best for Hands & Arthritis
For sore or arthritic hands rather than large muscle groups, the OUMIR Hand Massager combines heat with airbag compression, offering both hot and cold therapy across 3 modes, 3 intensity levels and 3 heating levels, with a design aimed specifically at carpal tunnel support.
It’s built around gently squeezing and warming (or cooling) the whole hand rather than a percussive massage gun approach, which suits people who find vibration or percussion uncomfortable on smaller joints.
OUMIR doesn’t appear to have an independent brand website or retail presence beyond this listing, so there are no independent reviews to draw on here, unlike the RENPHO and arboleaf picks above. The feature set is plausible and consistent with similar hand massagers from better-documented brands, but go in aware it’s an unproven brand rather than an established one.
Pros
- Airbag compression designed for arthritic hands
- 3 heat levels and 3 intensity levels
- Gentler than percussion for sensitive joints
- Specifically designed with carpal tunnel support in mind
Cons
- No independent brand presence or owner reviews found
- Only suits hands, not a general-purpose device
Key specs: Heat + airbag compression, 3 modes, 3 intensity levels, 3 heating levels.
6. KONGZEE Ice Machine for Knee – Best for Joint Cold Therapy
Unlike the massage guns and hand massager above, the KONGZEE Ice Machine is a genuine cold-therapy pump system, circulating chilled water through a universal flexible pad that wraps around a knee, shoulder, ankle, hip, back or leg, the kind of device often used after surgery or a sports injury.
It offers 5 adjustable flow levels and a programmable timer with presets up to 60 minutes, and KONGZEE markets it as leak-proof, crack-resistant, and quiet enough for overnight use. Dual carry handles and a mesh accessory pocket make it reasonably portable for a machine in this category.
KONGZEE’s own product page doesn’t display any customer reviews, so there’s no independent review sentiment to share for this specific model. If ongoing post-surgery or joint cold therapy is what you actually need rather than general muscle recovery, though, it’s a genuinely different category of device to everything else in this guide.
Pros
- Genuine circulating cold-therapy system, not just an ice pack
- Universal pad fits knee, shoulder, ankle, hip, back or leg
- 5 flow levels with a programmable timer
- Designed to be quiet enough for overnight use
Cons
- No independent reviews found on the brand’s own page
- Single-purpose device, only for cold therapy
- More expensive than the massage guns in this guide
Key specs: 5 flow levels, programmable timer (up to 60 min), universal TPU pad, quiet pump.
How to choose a hot and cold therapy device in NZ
Body area. A massage gun with a heat/cold head suits large muscle groups like the back, shoulders and legs, while a dedicated hand massager or eye massager is built for smaller, more sensitive areas. A cold-therapy machine with a wrap pad is designed specifically for joints, often after surgery or injury.
Heat vs cold vs both. Heat generally helps loosen tight muscles before activity, while cold is more often used to calm inflammation after activity or injury. A device offering both, like most in this guide, gives you the flexibility to use either depending on the day.
Percussion vs gentle compression. Massage guns use percussive movement, which some people find too intense on sensitive joints or skin, where a gentler compression-based device like a hand massager may suit better.
Battery life and charging. If you’ll use a device regularly, check battery life against your typical session length, and note whether it uses fast USB-C charging or a slower standard charger.
Brand track record. Established brands like RENPHO and arboleaf have independently verifiable reviews and their own websites, while some cheaper listings come from brands with no presence beyond a single marketplace listing. That doesn’t necessarily mean poor quality, but it does mean less independent feedback to go on.
If recovery matters as much as the training, the guides to TENS machines, massage chairs and portable ice baths are worth reading next.
Verdict
For most people, the RENPHO Active+ Thermacool is the easiest device to recommend here, backed by the strongest reviews in this guide and genuine app-guided routines. Anyone wanting the same idea at a lower price should look at the arboleaf massage gun, while the RENPHO Thermacool Deep Tissue is worth considering mainly if you find it discounted below the Active+.
For eyes and face specifically, the RENPHO Eyeris 3 is a genuinely well-reviewed, purpose-built option, and the OUMIR Hand Massager suits sore or arthritic hands better than a percussion gun would. If you need real joint cold therapy rather than general muscle recovery, the KONGZEE Ice Machine is the only device in this guide actually built for that job.
These are wellness and recovery devices, not medical equipment. They aren’t a substitute for professional medical advice, and anyone recovering from surgery, with a circulation condition, or with an open wound or skin condition should check with a doctor or physiotherapist before use.
FAQs
Should I use heat or cold for muscle pain?
As a general rule, cold therapy suits fresh injuries and inflammation, typically in the first 24 to 48 hours, while heat suits tight, stiff muscles and is often used before activity to loosen up. If you’re unsure which applies to your situation, a physiotherapist or doctor can advise based on the specific injury.
How long should a heat or cold therapy session last?
Most devices and guidelines recommend 10 to 20 minutes per session, with a break before reapplying if needed. Longer sessions don’t necessarily give better results and can increase the risk of skin irritation, especially with cold therapy.
Are massage guns with heat and cold heads worth it over a standard massage gun?
If you specifically want to add heat or cold to your recovery routine, a combined device saves buying separate tools, but a standard massage gun without the extra heads is usually cheaper if percussion alone meets your needs. It comes down to whether you’ll genuinely use the heat and cold functions regularly.
Can I use a hot and cold therapy device every day?
Many people use these devices daily for general muscle recovery or joint comfort without issue, but it’s worth taking breaks if you notice skin irritation, numbness, or increased pain. Devices used after surgery or for a specific injury should generally follow guidance from a doctor or physiotherapist rather than daily use by default.
Is cold therapy better than an ice pack after surgery?
A circulating cold-therapy machine, like the KONGZEE model in this guide, can maintain a more consistent temperature for longer than a melting ice pack, which is why they’re commonly used after knee and joint surgery. Always follow your surgeon’s specific aftercare instructions rather than substituting a device without checking first.
Can I use a heat and cold device on my face or eyes?
Only use a device specifically designed for the face or eyes, like a dedicated eye massager, since the skin there is thinner and more sensitive than on the body. Never use a standard massage gun’s heat or cold head directly on the face.
