I have those dates. The first 3s departed US for winter testing in June 2018. The demo cars departed June 2019 and the customer cars first departed US late July 2019.
It's possible they may keep one of these in NZ to sit in the Auckland showroom. It would save having to ship a separate showroom car over like they did with the Model 3.
