The first Bombardier Challenger to be registered in New Zealand took flight for the first time under its ZK markings on 29 April 2020. ZK-JCJ, operated by GCH (Garden City Helicopters) Jet Operations, was delivered to Christchurch back on 09 February 2020 as N604CA (SEE HERE) and was offically placed on the ZK register a couple of weeks later.
It's first flight as ZK-JCJ was conducted on the morning of 29 April 2020 when it conducted circuits at Christchurch, and it then flew onto Auckland. It then made a return trip to Taupo and back before heading back to Christchurch later the same day.
