For an older relative in New Zealand, pick a GPS tracker with reliable coverage in rural and urban areas, a simple interface with big buttons, and a long battery life. Look for real-time location updates, two-way calling, and fall detection. Ensure the device works with local networks like Spark or Vodafone, and check for a waterproof, durable design. Avoid complex monthly contracts; opt for a straightforward prepaid plan.
