Tips from locals
Passenger ferry services to Paihia. Also the local booking office for boat tours with Great Sites
There are many different cruises run by Fullers to the Islands. Swim with the dolphins, do the Cream Trip, go out to the hole in the rock and many more.
You can book cruises around the islands etc or a trip to Cape Reinga. Also see my other recommendation and see Collete at The Russell Information Centre
A great way to get out on the water. They offer a number of tours and chances of seeing Dolphins!
