I don't intend to speculate on the cause of the accident [see my Rules for assessing aviation news reports, below :-)], but it appears that the aircraft was a Skydive Taupo operated Pacific Aerospace 750XL, ZK-SDT. The following file photo is from last November when I was in Taupo.
Rodney's rules for assessing aviation news reports
- If it is published in the first week, it almost certainly contains critical errors
- If it's published by regular news media, it is almost certainly rubbish
- If it is published by aviation-specific media, at least 1-2 weeks after the accident, there might be a grain of truth in it
- If it is published by competent authority, after a full investigation [often 12-18 months after the accident], it's probably ok
