New Zealand.Kaikōura Lights

Between 21 and 31 December 1978, a series of sightings off the north-east coast of New Zealand's South Island, around Kaikōura and the mouth of the Clarence River, was recorded by cargo pilots, Wellington air traffic controllers and, in its climactic episode, by an Australian television crew that flew deliberately to document the phenomenon.

The first phase came in the early hours of 21 December, when the crews of Safe Air's Argosy freighters carrying the early-morning newspapers, among them those of Captains Vern Powell and John Randle, saw bright lights along the coast. The Wellington controllers, John Cordy and Andy Herd, reported echoes that appeared and disappeared near the Clarence River mouth and a target that, by their account, moved some 30 kilometres at about 120 knots. The succession of reports drew international media interest.

The filmed episode came on the night of 30 to 31 December. A crew from Melbourne's Channel 0, of the 0-10 group, made up of reporter Quentin Fogarty, cameraman David Crockett and sound recordist Ngaire Crockett, boarded an Argosy flown by Captain Bill Startup and co-pilot Bob Guard to film background material. On the southbound leg, Wellington controller Geoffrey Causer reported several anomalous targets near the aircraft; the technician with him, Bryan Chalmers, found that they vanished when the radar's moving-target processing was switched off. On the leg from Christchurch to Blenheim, at about 02:20, a very bright light appeared to the right of the aircraft; Crockett filmed it on 16 mm colour film, and the Argosy's weather radar, in mapping mode, showed a large echo in the same direction, at some 18 to 20 miles at first and closer later, according to the crew and reporter Dennis Grant, who had taken Ngaire Crockett's place on that leg. The Christchurch ground radar did not detect it.

The official investigation is in Air Force file AIR 1080/6/897, declassified by the Defence Force in 2010. The Air Force's press statement concluded that the sightings were 'the result of natural but unusual atmospheric phenomena': temperature inversions distorting light and radar waves, Venus, rising before dawn at its brightest, and more than fifty Japanese squid boats that had sailed from Wellington to a point 120 miles off Banks Peninsula, each carrying some 200 kilowatts of light; it added that the Wellington radar had for some time been giving spurious returns off that coast and that neither Christchurch nor Wellington recorded anything while the large light was being filmed. The DSIR interim report, signed by M. A. Collins on 12 January 1979, held that most sightings, made toward the east and low on the horizon from 3 a.m., were consistent with Venus seen through a disturbed atmosphere, and that Startup's light, seen some ten minutes before Venus should rise at that altitude, was 'classic' for a heavily refracted planet. A test of the windows of another Argosy concluded that the horizontal streaks on Crockett's film were window defects. The same report acknowledged two observations that did not fit: the airborne radar echo that accompanied Powell's light on 21 December, which it tentatively put down to meteors, and the large echo that accompanied Startup at about 16 kilometres, which a ground radar should have seen and which it attributed to an atmospheric reflection.

It combines 16 mm colour film, testimony from commercial pilots and a press crew, a recording of the communications with Wellington control, and radar echoes both on the ground and on board. That convergence of modalities is real, but the official file shows they match each other less than is usually told: the Wellington echoes were weak, vanished without moving-target processing, and the DSIR itself saw eighteen similar echoes on the night of 7 to 8 January with nothing visible in their direction; and the filmed light did not appear on any ground radar. The strongest correlation is the Argosy's weather radar, whose echo matched the light in azimuth according to Startup, Guard and the crew. Bruce Maccabee, an optical physicist at the Naval Surface Weapons Center, interviewed the witnesses, analysed the film and tapes and argued that his investigation ruled out Venus, the squid boats, ground lights and atmospheric effects; his report, which a New Zealand UFO group passed at his request to the Ministry of Defence and the DSIR, sits in the same file.

The official explanation has real explanatory power and should not be caricatured. Venus was at its brightest and rising in the east at the time of most sightings; temperature inversions were documented; the squid boats existed, though more than 100 kilometres away, and the pilots pointed them out to the passengers, as they did Venus at the end of the return flight, which suggests the crew could tell those lights apart from the object. The weakness of the explanation lies in the observation the DSIR itself left open: a large echo on the airborne radar, in the direction of the light, which it attributed to an atmospheric reflection without demonstrating it. In 2017 the New Zealand press publicised a document from the CIA archive describing the case as 'unique among civilian UFO reports' for the amount of documentary evidence; its wording matches Maccabee's analyses and there is no indication that it is the agency's own assessment. Kaikōura thus remains a divided case: the film alone admits a mundane reading, and the combination of light, airborne echo and professional witnesses is the only thing the official investigation did not close.
