While other countries in the world traditionally have Roast Turkey and Ham for Christmas dinner, we here in New Zealand are getting the "Barbie" Bar-B-Que fired up and wearing shorts and tee shirts.
Milford Sound and the West Coast of the South Island are having the traditional high rainfall, it is a rain forest region after all, and it is not uncommon to have rain throughout the country on Christmas Day. Despite officially being summer it has tended to be a little later in the last few years.
Hi Mark, It looks like Whangarei and Napier are the places to go for that little bit of extra heat! I’m planning a month-long trip to New-Zealand so this information has come in really handy. Thanks!
