Packing for Auckland in December means dressing for 21°C days and 15°C evenings. A light cotton tee with a casual overshirt works well at 21°C, the overshirt doubles as a layer for air-conditioned venues.

Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 11 potential rainy days.
Local tip: Layers are more practical than a single heavy garment in Auckland. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
