Case No. 247·New Zealand
1909·South Island (Southland and Otago), New Zealand
New Zealand.Airship Wave · New Zealand
Between June and August 1909, New Zealand had its own wave of mysterious 'airships', concentrated in the south of the South Island. The most cited case is Kelso (23 July): several schoolchildren and residents saw a craft over the school; a reporter interviewed them separately and obtained six strikingly consistent drawings of a blunt-headed cigar with two searchlights.

Incident
Limited evidence: single-witness, local or without primary verification. Three independent axes: the «tier» measures the strength of the evidence; the «probability» estimates how genuinely unexplained the case is —a natural phenomenon can remain unexplained, so it does not equal «non-prosaic»—; and the partition of explanations (below) says what it most plausibly was. So a well-documented case can have a possible hoax as its most plausible cause, and a Tier B is not, for that reason, a hoax.
Part 01
The night in question
Almost in parallel with the British 'scareship' panic, New Zealand experienced in 1909 its own wave of sightings of aerial craft impossible for the technology of the time. The activity began —and was most intense— at the far south of the South Island, in the Southland and Otago regions, where many settlements had flourished during the gold rush of earlier decades. There were earlier hints: a correspondent wrote to an Otago newspaper that he and two other men had seen a strange aerial light on three occasions during the winter of 1908, while trapping in Southland. The wave proper broke out between June and August 1909 and, as the weeks passed, the sightings seemed to move northward through the country before 'passing on' to Australia.
The best-investigated episode is Kelso, on 23 July 1909. A group of schoolchildren and some residents reported that an airship had come down and stayed 'bobbing' in the sky over the school for a few minutes. An Otago Daily Times reporter traveled to the town and, in a methodologically remarkable exercise for the era, interviewed the schoolchildren one by one, independently, and asked them to draw what they had seen. The result was six drawings whose degree of agreement and unanimity —in the reporter's own words— was 'dumbfounding even to skeptics'. All agreed on a blunt-headed cigar-shaped craft, fitted with two searchlights that swept the sky upward and in various directions.
At its peak, reports flooded the newspapers of the southern half of the South Island; the two Dunedin dailies —the Star and the Otago Daily Times— gave the phenomenon intense coverage. And then, as abruptly as it had begun, in mid-August 1909 the wave ceased in New Zealand. The 'phenomenon' seemed to migrate: from September, sightings were recorded in Australia, and the chain of phantom-airship waves would continue in the United Kingdom in 1912-1913, amid the escalating fear of a war with Germany.

Why this case moved the needle
The 1909 New Zealand wave matters to the corpus because it completes a decisive geographic triad —the United States in 1896-1897, the United Kingdom and New Zealand in 1909— demonstrating that the phantom-airship wave phenomenon was global and almost simultaneous across the Anglosphere, years before any aviation capable of producing it existed. Its distinctive and most valuable feature is the Kelso episode: the reporter who interviewed the schoolchildren separately and obtained six concordant drawings executed, unknowingly, a cross-corroboration protocol that remains the gold standard for evaluating mass sightings. That detail makes Kelso a case study in what witness agreement does —and does not— mean.
Because the drawings' agreement is real, but it does not imply a real object: it proves the children saw and described the same thing, not that that 'same thing' was a craft. That is why the posterior loads onto the mundane/misid narrative. The most economical explanation combines the misidentification of a bright celestial body (Venus dominated the southern winter sky) or ground lights with the powerful cultural frame of 'the airship' already installed by the international press, which gave shape to the ambiguous and unified the descriptions —including the recurring cigar-with-searchlights morphology, imported from earlier accounts. The small mass of indeterminacy acknowledges that we cannot audit witnesses from over a century ago nor reconstruct the exact conditions of each sky. In the corpus, New Zealand 1909 is the proof that a wave can be international, methodologically well recorded and yet entirely explicable as a perceptual and cultural phenomenon.

Distribution of explanations
This case is classified among the model's hypotheses: the bar splits 100% by how much each explanation weighs (the uncertainty is spread across the hypotheses the case supports). Summed across the corpus they produce the comparable partition. It is a different question from the Probability above: that one estimates how likely the case is a genuinely unexplained phenomenon; this one splits which the explanation would be.

Structured analytical judgment, not a calibrated frequency. Forced classification: the mass the evidence cannot assign is spread across the hypotheses the case does support.
