Astrophotographers are keeping a keen eye on Tuesday night's forecast, as the aurora australis could set the sky alight for a second night in a row.
Monday night's glow was the most impressive to grace the skies this year.
Photographer Christian Heinze-Rowney captured shots from the top of Christchurch's Port Hills - an unusual vantage point being so far north.

University of Canterbury Mt John Observatory director Associate Professor Karen Pollard told Newshub it was an impressive albeit unusual display.
The natural light display was the result of a solar storm on the sun.
"It's the interaction of the magnet field and the upper atmosphere particles," Pollard told Newshub. "But the bigger the storm, the bigger the aurora."
That's good news for the astrophotographers.
"There may be more activity tonight [Tuesday] if people go out and have a look because often it happens over several days," Pollard said.
Heinze-Rowney told Newshub it was worth the wait for the right conditions to explore the night sky.
