How to read this
Kp measures how disturbed Earth's magnetic field is, from 0 to 9. The higher it goes, the further the auroral oval spreads toward the equator. Invercargill lies at 50.2° geomagnetic latitude, so an aurora shows on its horizon from about Kp 7 or more, and overhead a couple of Kp steps higher. The sun goes well below the horizon every night of the year here, so any clear night can work. Get away from city lights and look south.
