Southern boobook taxa (southern plus Tasmanian boobooks and moreporks) as a single species. Examining both morphological and genetic (cytochrome b) characters in 2008, German biologist Michael Wink and colleagues concluded that the southern boobook is distinct from the morepork and Tasmanian boobook (which they proposed to be raised to species status as "Ninox leucopsis"), and that it is instead the sister taxon to the barking owl ("N. connivens"). A 2017 study by Singapore-based biologist Chyi Yin Gwee and colleagues analysing both multi-locus DNA and boobook calls confirmed a sister relationship of "N. n. novaeseelandiae" and "N." ("n.") "leucopsis" and their close relationship
Australasian Individual Speedway Championship Stadium in Auckland, was won by Maury Dunn. In the years 1970, 1971 and 1972, an Australasian Grand Prix meeting was held at the Liverpool Speedway in Sydney on the original "D" shaped track and not the bike track that was built on the infield in 1974 when the Liverpool track surface was changed to asphalt. All three Australasian GP's were won by New Zealand's Ivan Mauger. The first Australasian Final qualifier was held at the Western Springs Stadium on 21 February 1976 with dual Australian Champion John Boulger emerging as the winner. The last Final was held at the
