At 6pm on Sunday someone on the North Otago coast watched what looked like an aircraft on fire fall out of the sky and drop into the sea near Kakanui, a small settlement just south of Oamaru. They did the sensible thing and rang the police. Within minutes a search that assumed the worst was under way.
An hour later it was over, because the burning aircraft turned out to be a rock from space.
Dunedin police Senior Sergeant Iain Notman told the Otago Daily Times the inquiries that followed the call were “large scale, immediate, and extensive”. That is the standard response when a member of the public reports an aircraft going into the water, and it involves a lot of phone calls in a very short space of time.
The first task was working out whether anything was actually missing. Dunedin Air Traffic Control was contacted. So were the flight schools based at Oamaru and the commercial helicopter operators who work the district. Every aircraft was accounted for. The Rescue Coordination Centre New Zealand and Maritime New Zealand had no activations, meaning no emergency beacon had gone off anywhere near the coast. Flight Radar showed no flights in the area at all.
That is a reassuring set of answers, but it does not tell you what the caller saw. The picture only came together when southern police checked in with the national coordination centre and found they were not the only ones fielding calls. Reports had come in from Wellington, Christchurch and Dunedin, all describing the same thing, a red ball of light falling with what looked to be smoke trailing behind. Notman said the consensus was that this had been an atmospheric event down the east coast of New Zealand.
In other words, a fireball. Astronomer Dr Ian Griffin, quoted in the same report, put it plainly. “A fireball is a rock from space that’s burning up high over the Earth β¦ the really bright fireballs are caused by slightly bigger rocks.” It is the same thing as a shooting star, only much larger and much brighter.
What makes a fireball look so alarming is a combination of speed and distance. Objects entering the atmosphere are travelling at tens of kilometres a second, fast enough that the air ahead of them is violently compressed and heated, and it is that superheated air, rather than friction in the everyday sense, that produces the light. Most of the show happens somewhere between 80 and 30 kilometres up. The trail of what looks like smoke is a column of glowing, ionised gas and vaporised rock left hanging in the object’s wake, which can drift and fade over several minutes.
The distance is the part that fools everyone. A fireball burning up over the ocean a hundred kilometres away will appear to land just past the next headland, or in the paddock over the fence. Almost every person who has ever reported a plane going down and turned out to have seen a meteor made exactly the same error of judgement, and there is no obvious way for an untrained eye to avoid it. Seen low over water at dusk, a bright fireball with a trailing train genuinely does look like an aircraft on fire.
New Zealand does have people who watch for precisely this. Fireballs Aotearoa was set up in February 2022 by Professor James Scott of the University of Otago together with Dr Michele Bannister and Professor Jack Baggaley of the University of Canterbury. It now runs a network of more than 120 low cost Raspberry Pi meteor cameras, plus a wide angle Allsky7 camera, mounted on schools, observatories and ordinary houses from one end of the country to the other. Footage of the Sunday fireball crossing the Canterbury sky was credited to the network.
The point of all those cameras is triangulation. If the same object is caught from several angles, the group can reconstruct its path through the atmosphere and work out where any surviving fragments came down. That is how New Zealand got its tenth recorded meteorite. On 13 March 2024 a Queenstown man, Dennis Behan, spotted a bright fireball from his spa pool. Eight days later the network had calculated the trajectory well enough to plan a public search of the Mackenzie Country, and about 20 minutes into that search Jack Weterings of Wellington found a fragment sitting partly embedded in the ground south of Lake Tekapo. The TakapΕ meteorite weighed roughly 810 grams and is old enough to predate the planet it landed on. It is now held by Otago Museum.
Ten recovered meteorites in the country’s entire recorded history gives a sense of how unusual that outcome is. New Zealand is a narrow set of islands in a very large ocean, and most incoming rock either burns up entirely or lands in water, bush or high country where nobody is ever going to walk over it. There has been no suggestion that anything survived from Sunday’s fireball, and no search for fragments has been announced.
The other way to read the evening is as a system working the way it should. A member of the public saw something that looked like a disaster, reported it straight away, and within minutes several agencies had checked every aircraft in the district and confirmed nobody was in the water. Nothing about that was wasted. If you ever see something fall out of the sky and think an aircraft is in trouble, ringing 111 remains the right call, and no one will hold it against you if the answer turns out to be a lump of space rock.
Winter is the best time of year to see this sort of thing. The long dark evenings and the cold, dry air behind a southerly front give some of the clearest skies of the year, which is part of why so many people from Wellington south got a look at Sunday’s fireball.
