What is the high season, shoulder seasons, and winter like in New Zealand in terms of visitor numbers and availability?

New Zealand's high season in summer (December to February) attracts a peak number of tourists for beach activities and outdoor adventures. The shoulder seasons of spring and autumn offer a more relaxed atmosphere with fewer crowds, ideal for hiking and enjoying scenic beauty. Winter (June to August) sees ski areas bustling with visitors seeking snow sports, while coastal regions and major cities are less crowded. Winter travel may lead to better rates and availability, except in popular ski destinations. Travellers should plan for accommodations and activities during the high season and secure chains for winter driving.
