Metservice ended up calling this event a "Wind Storm" basically due to the fact no visual tornado was sighted. Personally im not convinced a tornado didnt happen as a rain wrapped tornado may not have been sighted.

This tragic event has been widely reported as a tornado. On Friday 7 December, as I wrote this blog, there certainly was an absence of evidence of a tornado. But absence of evidence is not evidence of absence. Over the last few days it has become increasingly clear — from inspecting aerial views of the damage swath, and from correspondence from people in the area at the time — that this was much more likely to have been a localised wind storm known as a microburst
