Description:
The Petrek GPS-4 MAX is the world’s smallest multi-network 4G pet tracker, featuring upgraded WiFi HomeZone technology to deliver increased battery life, improved indoor accuracy, and maximum coverage across New Zealand and Australia.
Building on the success of previous models, the 2026 GPS-4 MAX features a specially integrated multi-network SIM card that connects seamlessly to supported major mobile networks across the country—including One NZ, Spark, 2Degrees, and Skinny—rather than being restricted to a single provider. This dramatically reduces dead zones and offers unparalleled reliability whether your pet is at home, in rural areas, or travelling with you.
Weighing just 30 grams, the tracker easily attaches to your pet's existing collar with a durable silicone mounting case. The device integrates with the SafeTrek smartphone app (available on Apple iOS and Android) to deliver real-time mapping, rapid location updates, and custom boundary alerts.
Unlike typical GPS trackers that require expensive monthly subscriptions, the Petrek GPS-4 MAX offers a simple, all-inclusive annual service pricing model—with no separate mobile plans, top-ups, or contracts to manage.
Geo-Fencing & HomeZone
Set up virtual boundaries and receive mobile push notifications whenever your pet leaves the designated area. The combination of GPS tracking and WiFi HomeZone reduces false alarms caused by weak indoor signals.
Low Battery Alerts
Receive automated push notifications via the SafeTrek App when the tracker reaches low battery levels (requires active mobile reception).
Water Resistance & Maintenance
IP67 certified for daily protection against rain, mud, and shallow swimming. Note: Remove the unit from its case and rinse thoroughly with clean fresh water after exposure to mud or salt water. Ensure charging contacts are clean and completely dry before reconnecting the charging cable.

Guidelines:
Disclaimer: Please ensure to verify the mobile reception in your locality by referring to One NZ's coverage map.

Live Location + lightning mode
Receive live location updates on Google Maps with a precision of up to 0.5 meters by simply pressing a button. This feature helps you track the location of your pet accurately. You have the option to select the frequency of updates: every 30 seconds (Urgent mode), 5 minutes (Normal mode), or 2 hours (Power saving mode). The new GPS-4 device introduces a lightning mode, enabling you to prompt the device to update every second for 60 seconds. Please note that this functionality requires both GPS and GSM reception. The battery life varies depending on the chosen settings.
Satellite View
The availability of satellite imagery and other live views is subject to GPS signal. In the absence of GPS signal, the app will provide information on the nearest cell tower as a reference until the tracker regains reception in a suitable area.
Street View Technology
The presence of a built-in Google map allows users to access street view and discover the location of their dog or cat within a specific property or building.
The accuracy of each update is heavily reliant on the strength of the GPS signal. Inaccuracies are more likely to occur in scenarios involving minimal movement or confined spaces, particularly indoors or under cover. Although they are infrequent, these inaccuracies can differ by 500m+ or more. Therefore, it is advisable to verify the GPS signal strength to ensure the accuracy of each update, especially when uncertain.
Geo-Fencing
Geo-Fencing relies on GPS signals for the Petrek to update its location. As long as the tracking is moving (not in sleep mode) and outdoors, the breach will be picked up. Please also note that a GSM network is required to send the notification to your phone.
Geo-fencing false alarms may occur if your pet enters neighbouring properties due to potential limitations in GPS signal indoors or when the tracker is obstructed by the pet or surrounding objects. It is important to note that this is not a flaw, but rather a characteristic of this situation. However, the new Wifi HomeZone mode has been designed to mitigate this issue by accurately detecting if your pet is within its own home or nearby using your wifi network.
Low Battery Alert
When your Petrek GPS is about to run out of juice, you will receive a notification viathe SafeTrek App
*Low battery alert applies only if there is GSM signal. If the tracker is in an area with no GSM reception, you may not receive the alert.
Battery Life
The new Petrek GPS-4 Wifi HomeZone mode is anticipated to boost battery life by up to 40% for pets who spend more time at home. For pets with higher outdoor activity, the approximate battery life is indicated below. When the Petrek unit doesn't detect movement, it automatically enters sleep mode, lasting up to 1600 hours in this state. However, the actual battery life may significantly differ based on your pet's activity level, update frequency, and enabled features.
- Normal mode (5-10 min updates) - Approx 7-10hours
- Urgent mode (30 Sec updates) 3-5 hours
- Power saving mode (2 hour updates) 2-3 days
Battery life may vary depending on usage levels. In areas with poor reception, such as being indoors away from home, the battery life can decrease by up to 2 hours from the usual ratings.
However, if your pet is often in open areas where the tracker doesn't need to constantly search for better reception, the battery life will improve. For more information, please refer to our FAQ. Please note that switching back from Power saving mode may take up to 20 minutes, provided that the tracker is in an open area with GPS signal and cell reception. During this time, the Petrek unit will go to sleep for 2 hours to conserve power. However, if the Geo-fence is triggered on the next update, a notification will be sent and the tracker will switch back to "normal" mode.
IP67 Waterproofing + SIM card costs/info
Yes, the Petrek 3G is certified and has passed its IP67 ratings. This means your dog or cat can swim at the local swimming pool for up to 30 minutes, as long as they don't dive deeper than 1 meter. Remember to remove the device from the case for a fresh water rinse and clean afterwards.
*IP67 rating does not allow the tracker to be used for deep water diving. Warranty will not be given if water damages are found.
Please make sure to recharge the SIM card in your Petrek device with a minimum of $20 using One NZ Fastpay or $10 via One NZ Customer account annually. Failure to top up the SIM within 13 months of the initial or most recent top-up will lead to deactivation by One NZ. If deactivation occurs, please return the device for a SIM replacement. Additionally, after the second year, you will be required to renew the Google Map fee of $15 USD through the app.”

Reviews
"Highly Rated Tracker and Customer Support"
Posted byNatashaon2nd Oct 2026I love this tracker, I know exactly where my cat is at all times, also my daughters cat who is added to my app as well. so easy to use and set up. I chose this device from others because I didn’t want to be paying a monthly fee to some overseas company! I only pay $20 a year to keep SIM card alive, super cheap! I have recommended this tracker to all my friends. Great customer relations, very quick to respond to any queries and super friendly. Buy one, you won’t be disappointed
"WAY overly complicated to set up and doesn't work!"
Posted bycatherineon30th Sep 2026We have a dog that tends to go walkabout when she is at work on the vineyard with my husband, so we got one of these trackers about a week ago. I chose this one because there wasn't a monthly subscription but we still had to pay $75 to activate it and another $10 to One NZ on top of the $200 to buy the tracker. The app is extremely clunky and hard to set up, and now my husband is at work with the dog and can't find her, and the app is showing her location is still near our house, 30 minutes away! So all that money spent and it isn't even working properly. Would not recommend.
