The top packing tip for a New Zealand vacation is to ensure you pack layers in your suitcase. Four-seasons-in-one-day weather means the temperature can change in a minute, with essentials including a waterproof jacket and windproof jumper needed to keep warm and dry when it rains or turns chilly. Always carry a hat and sunscreen – the Southern Hemisphere sun will burn even in inclement weather – and comfortable shoes are mandatory. A thermal layer and beanie could be considered assets during autumn and spring, as well as winter, and swimmers are not just for summer with thermal pools and hot-water streams just as agreeable in winter as a beach dip is during the summer months. Remember a power adapter with New Zealand uses type I plugs, bring insect repellent, pack personal medications, carry a reusable water bottle, and throw in a powerpack to keep devices charged.
