Aurora Viewing Guide
Quick Answer: Stewart Island in New Zealand sits at -53.4° geomagnetic latitude, requiring a minimum KP index of 4 for aurora visibility. The best viewing months are Mar to Sep, with up to 15 hours of darkness during peak season. Average cloud cover is 60% during aurora season, and the area has Bortle Class 1 dark skies.
Stewart Island (Rakiura), New Zealand's third-largest island, offers the country's best aurora australis viewing. The island's name in Maori, "Rakiura," translates to "glowing skies," a reference to the aurora australis that has been observed here for centuries. With virtually zero light pollution (Bortle 1), even faint aurora displays are visible. The island is accessible by ferry from Bluff.
At a geomagnetic latitude of -53.4 degrees, Stewart Island requires a minimum KP index of 4 for aurora to become visible. NOAA describes that activity level, "Active", as: Strong aurora display. Visible across much of Scandinavia and northern North America. Multiple colors and dynamic movement. Average cloud cover here during aurora season is 60%, so plan for some cloudy nights; staying more than one night improves your odds of a clear sky.

A sheltered bay on Stewart Island's northern coast near Oban. The Maori name for the island, Rakiura ("glowing skies"), refers to the aurora australis visible here for centuries.
A short walk from Oban village leads to a rocky outcrop with panoramic views over Paterson Inlet and Foveaux Strait. The elevated position provides clear sightlines south.
A remote west coast beach accessible by a multi-hour hike or water taxi. The complete isolation and Bortle Class 1 skies make even the faintest aurora australis visible.

Yes, Stewart Island is a good location for viewing the southern lights. You need a minimum KP index of 4 here. The best months for viewing are Mar to Sep.
Stewart Island requires a minimum KP index of 4 to see the southern lights. NOAA classifies KP 4 activity as "Active", occurring occasional (4% of nights). Higher KP values produce brighter aurora that covers more of the sky.
The best months to see the southern lights in Stewart Island are Mar to Sep, when up to 15 hours of darkness are available each day. Give your eyes time to adjust to the dark before judging whether aurora is visible.
Start with ISO 1600 to 3200, an aperture of f/2.8 or wider, and a shutter speed of 8 to 15 seconds. Use a wide-angle lens (14 to 24mm) on a sturdy tripod, and focus manually on a bright star or distant light before the aurora appears.
