A chance to glimpse a kiwi in the wild, experience the spectacular dune environment and wild west coast beach and learn about the natural history and early European history of the area… View an array of ecosystems and wilderness habitats, from east to west coast and across Stewart Island's interior. Enjoy a variety of native and endemic birds and plants, including orchids in season. Experience a stay in a backcountry hut!
See also Kiwi, Dunes & Beach, which offers an extra day at Mason Bay to explore the dune and beach environment.
The middle section of Stewart Island from west to east coast comprises: Mason Bay, the Freshwater Flats / Freshwater Valley and Paterson Inlet.
Mason Bay has approximately 14 kms (9 miles) of curved beach, one of the most extensive natural sand dune systems in New Zealand with native coastal plants, some sea and shore birds and a population of kiwi. A great place to go kiwi spotting, enjoy the stunning seascape, watch the surface crash on the beach and feel at one with nature!
Coastal forest, tussock, grasses and scrub surround Mason Bay. Further inland, the surrounding northern and southern hills slope down to an extensive wetland area - the Freshwater Flats. A multitude of creeks that run through the flats feed water into Freshwater River. The river meanders down to its estuary at the start of Paterson Inlet, releasing tannin stained water and silt. The changing habitat, allows a variety of native and endemic birds and plants to exist in the area.
Our trips provide an opportunity to discover kiwi habitat, listen to kiwi calling in the night and with some luck, actually seeing a kiwi. Our success rate for sighting kiwi is about 90%, with 80% seen during the daytime. Kiwi are wild birds and sightings are not guaranteed. It is a privilege to see a kiwi, an experience that many clients never forget!

"Furhana led us through constantly changing vistas of bush and wetland, pointing out native birds along the way, including the Stewart Island robin and fernbird. Nothing could have prepared us for our first sighting of a Stewart Island brown kiwi, though – foraging on the forest floor in broad daylight, while we quietly looked on.
Climbing the dunes and standing on the vast, empty beach at Mason Bay was a beautiful end to the day's walk (sore feet aside!), rounded off with a dinner of fresh blue cod at the hut where we would spend the night before journeying back the next day."
