Best Period to Go: Auckland is a wonderful city. I've been twice and I can tell you that the New Zealand summer is perfect. Never too hot, with temperatures that don't exceed 24°. There's always a breeze that tempers the air and you don't suffer from the heat, so much so that we hardly ever went out in short sleeves.
Best Period to Go: The warm high season can be experienced during the months of November to April and it is even suitable for outdoor exploration. The summer season from December to Febraury is convenient for food and wine concerts, festivals and such sport events. However, the month of December to the far north can be rainy and if a person is more of a snow bunny, he can visit the city of Auckland when snow is thick from June to August and try for skiing.
