Harvey Cooke

Harvey Cooke was a New Zealand UFO researcher best known for his meticulous investigation of the Ngatea Circle—a mysterious formation discovered in 1969 on farmland in the Hauraki Plains. Though he never experienced a UFO sighting himself, Cooke dedicated approximately fifty years to ufological research, gaining recognition through television and radio appearances, conference organization, and his tireless fieldwork documenting alleged anomalies.

Cooke served as president of the Tauranga Science Space Research Group and founded and directed TUFOIG (Tauranga UFO Investigation Group), which he operated for 55 years—one of the world's longest-standing organized UFO investigation bodies. His approach was marked by rigorous measurement, sample collection, and collaboration with academic institutions, particularly the University of Auckland's UFO research unit.

The Ngatea Circle Investigation (1969)

In September 1969, Cooke began investigating a circular formation discovered on a Hauraki Plains farm near Ngatea. His measurements revealed three sharply defined, evenly spaced V-shaped depressions in the earth, arranged in a precise equilateral triangle. The physical evidence suggested that whatever created the marks had exerted approximately 20 tonnes of pressure per contact point.

Most striking was Cooke's discovery that the carbonized pith of affected trees showed unmistakable signs of internal combustion—the wood had been cooked from the inside outward, with no evidence of external scorching or thermal damage. This characteristic pattern suggested rapid exposure to intense short-wave, high-frequency radiation rather than conventional fire. After consulting with University of Auckland researchers and conducting soil and vegetation analysis, Cooke released his findings on October 6, 1969, concluding that "some kind of short-wave high-frequency radiation has cooked the material from the inside outwards," adding that he knew "of no earthly source of energy which could have produced these effects."

His findings gained traction in ufological circles and remain cited in discussions of alleged physical evidence for craft landings. However, the site's investigation was complicated within weeks when the Department of Scientific and Industrial Research (DSIR) dispatched its own team. Unable to take definitive measurements due to the site having been trampled by thousands of curious visitors, DSIR concluded that a saprophytic fungus (a type of wood-decay organism) had caused the markings. Cooke immediately disputed this analysis, noting correctly that such fungi attack dead wood but do not cause tree death, and certainly cannot explain the thermally anomalous internal carbonization he had documented. He remained adamant for the rest of his life that the Ngatea Circle was the result of visiting extraterrestrials.

Legacy and Approach

Cooke's significance in ufology lies not in dramatic personal claims but in his commitment to systematic investigation and documentation. He embodied a tradition of earnest, community-based UFO research that characterized much of twentieth-century ufological work. His willingness to engage academic institutions and challenge official explanations demonstrated intellectual integrity, even as his conclusions remained outside mainstream scientific acceptance.

Cooke's death in December 2007 marked the end of a research career spanning roughly five decades. While the Ngatea case remains contested, his methodology—careful measurement, sample collection, stakeholder consultation—set a standard for physical-evidence investigations in UFO research. His work is regularly revisited in New Zealand ufological discourse and has attracted renewed international attention, including investigation by U.S.-based researchers in 2025.
