In summer (from December to February), when the temperature stays at a comfortable level of around 18–22°C, you will need t-shirts, light trousers, and shorts.

Regardless of the time of year, take comfortable and, preferably, waterproof walking shoes with you to comfortably explore the city streets and natural attractions. Also, do not forget about the specifics of the New Zealand climate: the sun here is very active even on cloudy days. Be sure to bring sunscreen with a high protection factor, sunglasses, and a hat to protect yourself from UV rays during walks.
