The best kids smart watch in NZ overall is the 4G Kids Smart Watch with 2-Way Calling & Camera, because it combines GPS positioning, two-way calling, an SOS button and WiFi-assisted location in one touchscreen watch that works without a nearby smartphone. Every pick below is a 4G kids watch currently sold in NZ, and each one is built around a different family need rather than one universal “best” spec sheet.
These watches sit apart from a general-purpose smart watch or a step-counting fitness tracker: their whole job is keeping a parent in contact with a child and showing where that child is. Bestdeals, the NZ retailer stocking all five picks, does not publish full spec sheets for this class of watch, so screen sizes, battery figures and app behaviour below are drawn from the hardware family each model belongs to and from real owner feedback on that class of device, with every claim that could not be independently confirmed flagged as such.

The Best Kids Smart Watch NZ
1. 4G Kids Smart Watch with Calling & Camera – Best for Overall

This is the best kids smart watch in NZ overall because it puts a front camera, two-way calling, an SOS button, WiFi-assisted location and an activity monitor on one wrist, without leaning on a nearby phone.
The case is a rounded rectangle sized for a child’s wrist, worn on an adjustable silicone strap in a bright purple colourway with a glossy plastic bezel around the colour touchscreen. Watches in this hardware class typically run a 1.4 inch to 1.83 inch touch display, and this listing’s full-touch interface handles calling, the camera and the activity monitor from the same home screen.
Setup runs through a SeTracker-style companion app: parents register the watch using its ID number, add up to ten approved contacts, and switch on geofencing or a scheduled do-not-disturb window from their phone. The SOS button, held for a few seconds, dials through those saved contacts in turn until someone answers. Location comes from three methods layered together: GPS outdoors, WiFi hotspot matching indoors, and mobile base-station positioning as a fallback, which is the least precise of the three and can be out by hundreds of metres.
Video and voice calling run over 4G, so the watch needs its own nano SIM and a small data plan, not a phone pairing. Battery life in devices of this class runs closer to a day of mixed calling and GPS use than the multi-day standby figures often quoted, and the front camera is better suited to casual video calls than sharp photography. Screen protectors are worth adding, since the plastic touchscreen scratches easily with rough handling.
Pros
- SOS, GPS, WiFi location and video calling combined on one device
- No phone needed nearby once a SIM is inserted
- Companion app supports geofencing and a do-not-disturb schedule
Cons
- Indoor location falls back to less accurate base-station positioning
- Battery drains faster with active video calling than standby claims suggest
- Camera quality suits calls rather than detailed photos
Key specs: 4G calling, GPS/WiFi/LBS location, SOS button, front camera, activity monitor, purple colourway.
2. 4G Kids GPS Smart Watch with Video Call – Best for Water Resistance

This model is the pick for families who need a kids’ watch that can survive spilled drink bottles and rainy bus stops, because it carries an IP67 rating on top of the usual GPS, video calling and SOS features.
It shares the same general form as most watches in this class: a touchscreen face on an adjustable silicone strap, finished here in black with a matte bezel. Bestdeals markets it around an “ultra-clear large screen” and an “ultra-thin” body, and the model sits in the same 1.4 inch to 1.83 inch touchscreen family as the other watches in this guide.
IP67 means the casing is dust-tight and can survive brief accidental immersion, roughly a metre of water for around 30 minutes, which covers rain, sink splashes and a dropped watch in a puddle. It is not a swimming rating, and repeated exposure to pool chlorine or long showers can still let moisture past the seals over time. Positioning again blends GPS, WiFi and LBS base-station modes, with a history-route feature that logs where the watch has been through the day so a parent can review a route after the fact, not just a live pin.
Real-world feedback on this device class flags the same two weak points repeatedly: GPS accuracy softens indoors, and the companion app can be clunky to register on first setup. Battery life leans toward a day or two of mixed use rather than a week of standby once video calling is switched on.
Pros
- IP67 dust and splash resistance beyond the class norm
- History-route tracking, not just a live location pin
- Large, clear touchscreen for its price point
Cons
- IP67 is splash-proof, not swim-proof
- App registration can be fiddly on first setup
- Indoor GPS accuracy softens to base-station estimates
Key specs: 4G video calling, IP67 rating, GPS/WiFi/LBS tracking, SOS call, history route, black colourway.
3. 1.83-Inch 4G Kids Smart Watch – Best for Video Calling & Photos

For families who want their child to actually enjoy using the watch rather than tolerate it, this 1.83 inch model earns its place with the largest screen in this lineup and a dedicated photo-taking mode alongside its safety features.
The 1.83 inch panel is noticeably roomier than the 1.4 inch screens used on cheaper watches in this guide, and the same body ships in black, blue and purple across bestdeals’ listings, which points to a shared design across the range. Reviewers of comparable 1.83 inch kids watches describe the touchscreen as full HD and responsive for a device this size, running on the same silicone-strap, plastic-case build as the rest of the category.
A one-click SOS button sits alongside GPS positioning and video calling, so the safety basics match the other watches here, but the bigger screen and built-in camera shift the emphasis toward a child wanting to use the watch, not just wear it. Photos and video calls both benefit from the extra screen real estate for framing a shot or seeing who is calling. As with the rest of this class, the camera is a basic sensor rather than a sharp one, better for a quick selfie or video chat than anything a child will want to print.
The trade-off with a bigger touchscreen is more surface to scratch and a slightly bulkier case on a small wrist, so this suits a child old enough to be trusted with a less compact device.
Pros
- Largest, clearest screen in this lineup at 1.83 inches
- One-click SOS plus GPS positioning and video calling
- Available in black, blue and purple
Cons
- Bigger screen means a bulkier case for smaller wrists
- Camera resolution is basic, fine for calls rather than photography
- No independently confirmed battery figures for this exact listing
Key specs: 1.83in touchscreen, 4G video calling, one-click SOS, GPS positioning, photo mode, black colourway.
4. 4G Kids Phone Watch with GPS Tracker – Best for Gifting

Marketed squarely as a birthday or Christmas present, this blue GPS tracker watch is the pick for anyone buying for someone else’s child, since it covers the full safety feature set without asking the buyer to make a technical trade-off.
It uses the same core hardware as the purple overall pick: a touchscreen face, adjustable silicone strap, front camera and SOS button, sold here in blue with a matching black-cased sibling listing at a higher price on the same site. That pairing suggests one base watch reused across several bestdeals colourways rather than a genuinely distinct model, which is worth knowing before paying a premium for a colour alone.
Two-way calling and the GPS tracker run through a nano SIM and a small NZ data plan, and setup follows the same companion-app pattern as the rest of this guide: register the watch’s ID, add trusted contacts, and switch on location sharing. As a gift, the appeal is straightforward unboxing and a recognisable feature list a non-technical buyer can describe confidently: calling, camera, SOS, WiFi and GPS.
The honest caveat for gift buyers is that the watch is not immediately usable out of the box. It needs a nano SIM sourced separately, a data plan activated, and the app set up before the recipient’s child can make a call or be located, so it suits a buyer willing to do that setup themselves or walk the parent through it.
Pros
- Full calling, camera, SOS and GPS feature set
- Recognisable, easy-to-describe gift for non-technical buyers
- Blue colourway distinct from the darker options in this guide
Cons
- Needs a separately purchased nano SIM and data plan before first use
- Appears to share hardware with a pricier black sibling listing
- No camera-resolution or battery figures published for this exact listing
Key specs: 4G two-way calling, camera, SOS button, WiFi and GPS tracking, blue colourway.
5. 4G Kids Smart Watch with School Mode – Best for School Days

This is the pick for parents whose main complaint about kids’ watches is the classroom disruption, because School Mode is built into the name and the core feature of this 1.4 inch model.
It is the simplest and most compact watch in this guide, with a 1.4 inch touchscreen on an adjustable silicone strap, and it is also the only one of the five without a listed camera, trading that feature for a smaller, lighter case better suited to a younger or smaller wrist. School Mode is a parent-set do-not-disturb window, scheduled through the companion app to match class hours, that silences calls, messages and games on the watch face while leaving GPS tracking and the SOS button running in the background.
Outside school hours it covers the same basics as the rest of this guide: 4G two-way voice and video calling over a nano SIM, GPS positioning, and an SOS button that dials saved contacts in sequence. Because it sits at the lower end of this lineup’s feature list, expect the same trade-offs common to budget kids watches: single or dual-band 4G that may limit coverage in some rural areas, and GPS accuracy that softens indoors in the same way as every other watch here.
For a first watch aimed at a younger child, the smaller screen and missing camera are arguably an advantage: less to break, less to distract with during school hours, and one less lens for a young child to worry about pointing correctly.
Pros
- School Mode silences the watch during class hours automatically
- Smallest, lightest case in this lineup, suited to younger kids
- Still covers 4G calling, GPS and SOS basics
Cons
- No camera, unlike every other pick in this guide
- Budget-tier hardware may mean narrower 4G band support
- GPS still relies on the same base-station fallback indoors
Key specs: 1.4in touchscreen, 4G two-way voice and video calling, School Mode, GPS tracking, SOS button.
How to Choose the Best Kids Smart Watch in NZ
SIM card and data plan: Every 4G kids watch in this guide needs its own nano SIM and a small prepaid or account plan, since the calling and GPS features do not run through a paired phone. Spark, One NZ, 2degrees and Skinny SIMs all work as long as the plan includes voice calls and roughly 0.25GB to 1GB of monthly data; heavier video-call use will need more.
Check it is genuinely 4G: One NZ is retiring its 3G network and Spark and 2degrees have already wound back older networks, so a kids watch that only supports 2G or 3G will stop working on some or all NZ networks. Confirm 4G support before buying rather than assuming any “smart watch” listing qualifies, since older stock can still turn up in NZ online stores.
GPS accuracy is layered, not absolute: These watches locate a child three ways: GPS, which is accurate outdoors; WiFi hotspot matching; and mobile base-station (LBS) positioning, which is used as a fallback indoors and can be out by hundreds of metres. If precise pet-style tracking matters more than calling, it is worth comparing these against a dedicated pet GPS tracker built solely around location accuracy.
Match the screen to the child’s age: Smaller 1.4 inch screens, like the School Mode pick in this guide, suit younger children who mainly need calling and an SOS button. Older kids tend to prefer the larger 1.83 inch touchscreens with cameras and games, similar to how a budget tablet with a bigger screen suits an older child better than a small one.
School Mode and parental controls: Look for a companion app that supports a scheduled do-not-disturb window, a short contact list, and geofencing, so the watch stays useful for safety without becoming a classroom distraction.
Water resistance has limits: An IP67 rating covers dust and brief accidental splashes or immersion, not swimming or long showers. Treat any “waterproof” kids watch as splash-resistant rather than swim-proof unless the listing states an actual swim rating.
Battery and warranty expectations: Standby-time claims rarely hold up once video calling and GPS polling are switched on, so expect closer to a day or two of active use rather than a week. Bestdeals-sold watches carry a standard 30-day change-of-mind return window and warranty cover under the NZ Consumer Guarantees Act, so keep the original packaging until the watch has been tested.
If the goal is simply an active, screen-free gift for outdoor play rather than a phone-replacement device, it is also worth weighing a kids scooter or similar physical gift against a smart watch.
Verdict
For most NZ families, the 4G Kids Smart Watch with 2-Way Calling & Camera is the best all-round buy, because it covers calling, GPS, WiFi location and an SOS button without asking for a compromise. Families who need extra durability should lean toward the water-resistant pick, those buying for an older child who wants to enjoy the watch should choose the 1.83 inch model, gift-givers can rely on the blue GPS tracker watch, and anyone buying for a younger child starting school should choose the School Mode pick to keep the watch out of the classroom.
FAQs
Do kids smart watches in NZ need their own SIM card?
Yes. 4G kids smart watches take a nano SIM with an active data and calling plan, sold separately from the watch. Spark, One NZ, 2degrees and Skinny SIMs all work as long as the plan includes voice calls and roughly 0.25 to 1GB of monthly data for GPS pings and video calls.
What age is best for a kids smart watch?
Most kids smart watches suit children aged roughly 5 to 12, once they are old enough to charge the watch, answer calls and understand the SOS button. Younger children often do better with a simpler 1.4 inch screen, while pre-teens tend to prefer larger touchscreens with cameras and games.
How accurate is GPS tracking on a kids smart watch?
These watches locate a child three ways: GPS (most accurate outdoors), WiFi hotspot matching, and mobile base-station (LBS) positioning, used indoors and able to be out by hundreds of metres. Expect strong accuracy outside and a rougher estimate inside schools, buses or shopping centres.
What does School Mode do on a kids smart watch?
School Mode is a parent-set do-not-disturb window, usually managed through the watch’s companion app, that silences calls, messages and games during class hours while keeping GPS location and the SOS button working in the background. Parents typically schedule it to match school start and finish times.
Will a 4G kids smart watch keep working as NZ switches off 3G?
Yes, provided the watch is genuinely 4G-capable rather than an older 2G or 3G model. One NZ is retiring 3G, and Spark and 2degrees have already phased out or are phasing out older networks, so confirm 4G support before buying rather than assuming any smart watch listing qualifies.
