Bonjour,
Voici un début:
When planning your trip to New Zealand, remember to consider that the seasons are reversed on the other side of the world. The summer is from December to February and the winter from June to August. Avoid visiting New Zealand in winter as it rains a lot and as an "outdoor" destination you will find it difficult to make the most of your trip if you leave this season. Summer remains the best period with temperatures hovering between 20 and 30 degrees depending on the day. Note that in the South Island, it's still a few degrees less than in the north!
J'espère avoir pu vous aider, n'hésiter pas si vous avez des questions :)
