In 1998, Justice Johnstone then took up a role at Meredith Connell, conducting District Court and then High Court jury trials and regulatory prosecutions, and civil proceedings under the Proceeds of Crime Act 1991.
He became a partner at Meredith Connell in 2005 and had been a member of the Serious Fraud Office’s prosecutors’ panel since 2014.
Earlier this year, Johnstone left Meredith Connell to join the independent bar.
Johnstone has been involved in a number of high-profile cases, including the Desert Road murder case after the disappearance of Bao Chang “Ricky” Wang and the Labour Party ‘summer camp’ sexual assault trial in 2019.
He also acted in the first case in New Zealand seeking pecuniary penalties for breaches of the Anti-Money Laundering and Countering Financing of Terrorism Act. Auckland firm Jiaxin Finance and its mother-and-son operators were handed millions of dollars in court-ordered fines after failing to report $53.4 million of suspicious transactions from international mogul Edward Gong, who was accused of running a pyramid scheme.
And Johnstone appeared in the FMA prosecution against Paul Bublitz, Bruce McKay and Richard Blackwood in 2019, for their crimes committed during the global financial crisis after the collapse of two finance companies which left investors short $17 million.
Johnstone will take up his High Court appointment on February 22 next year, sitting in Auckland.
