There are loads of places and things to do. What do you like doing?
A lot of people in NZ now get married at the beach,rose gardens or even in someones garden. My daughter who's only 14 want sto get married on a boat with Dolphins swimming around her.
Here are some links to look at.
A couple of years ago I went to a cousins wedding at The Mudbrick which is at Waiheke Island, Auckland . It was the most stunning wedding I have ever been too. The bride organised for the bridal party only these little white pieces of paper and she said now open them very carefully and then out popped Monarch Butterflies, it was amazing.
