What do Kiwis commonly call the summer holiday period?

Kiwis commonly refer to the summer holiday period as the Christmas/Summer holiday. This terminology reflects the unique overlap of the festive Christmas season with the long summer break in New Zealand, which typically spans from late December to late January. During this time, many families take vacations, celebrate the holidays, and participate in various outdoor activities, aligning with New Zealand's warm summer weather. This period is significant for cultural and traditional celebrations, making the term both practical and culturally relevant. The other options do not capture this specific combination of holiday and seasonality that is uniquely characteristic of the New Zealand experience during these months.
