Best time to visit Bay of Islands
The month-by-month edit — when Bay of Islands actually opens up, when to avoid it, and how crowds and hotel rates move through the year.
The short answer
When Bay of Islands is at its best
The Bay of Islands is New Zealand's sub-tropical north — 144 islands across a sheltered bay three hours' drive (or a 35-minute flight) from Auckland, with a sailing and snorkelling culture closer to the Whitsundays than to the South Island alpine country. The right trip is three or four nights at a single lodge — Helena Bay, Eagles Nest, or the heritage Lodge at Kauri Cliffs — paired with a sailing-charter day around the islands and an afternoon at the Waitangi Treaty Grounds.
