Captured by the events unravelling in front of them, the left-hand light moved slowly away while the one on the right did exactly the same movement in a horizontal direction, she said.
The pair tried to document it on Mr Daintith's phone but were unable to.
As they fumbled with the camera one light turned sharply like a helicopter and seemed to move closer and closer, she said.
"I don't know how far it was away, it could have been a long, long, way but I know it was quite big and getting bigger and brighter.
"Then it just did another sharp turn and moved away. The one in the middle stayed were it was before it faded and disappeared."
All the way home the Daintiths tried to convince themselves that "things like this don't happen; there has to be an explanation," she said. "My husband does not believe in ghosts or UFOs and is a former aircraft engineer but even he said that was very strange."
Tauranga Astronomical Society president Stuart Murray said Tuesday was a particularly fascinating as both "Venus and Jupiter were in a straight line looking at the moon."
"They were especially brilliant because the air was very clear and they almost looked like car headlights, they were so bright and clear. It was spectacular." That night there were people at the observatory with the roof open and looking through telescopes from 7.30pm to about 9.30pm, he said.
However, Mr Murray said you would not see the planets moving if you were standing still and they did so slowly.
Niwa atmospheric scientist Dr Richard Querel said on Tuesday night the Aurora Australis, also known as the Southern Lights, (caused by eruptions on the surface of the sun) would be more likely to be spotted along the horizon while the planets that aligned were higher up. The geomagnetic storm was normally only seen in the South Island, but was so big it was spotted off the North Island's east coast. To see the Aurora you would have to be looking south if there were any strange flashes, he said.
"Sometimes it looks like bright lit-up clouds along the horizon."
Tauranga Airport manager Ray Dumble said nothing unusual had been reported but it did field calls about unexplained lights in the night.
