Explore the wineries of Waiheke Island! We had the best day visiting Waiheke from Auckland. Here is how to make the most out of one day on the island with extra spots saved. We made it a long day and didn't get to visit all the spots we wanted to, so even better would be to spend the night on the island and have 2 days there! We focused on wineries and food, but there are beaches and other activities as well.
