As a former Crown Counsel at the Crown Law Office, Policy Manager at the Ministry of Justice, public sector in-house counsel and Crown Prosecutor, Gregor understands public sector decision-making. He is well-placed to advise private and government entities on a range of matters relating to legislation and the exercise of public powers.

Gregor is a member of several Government counsel panels. He has recently acted for a range of Crown entities, including The Treasury, Inland Revenue Department and Office of Treaty Settlements. He has also acted for a number of enforcement agencies such as the Financial Markets Authority, Civil Aviation Authority, the (former) Ministry of Fisheries, Police and Customs. He holds the highest level of security clearance. He can assist on matters that have implications for national security or otherwise require access to classified information and has been appointed on such matters by the High Court and intelligence agencies.

Gregor has particular experience with inquiries. He has assisted public reviews and was counsel for the Crown before the Royal Commission of Inquiry into the Canterbury Earthquakes. He has provided advice on significant fraud investigations and, as a former Assistant Director of Public Prosecutions for Fiji, guided serious criminal investigations, including into mutiny and treason. He is on the Serious Fraud Office Panel of Prosecutors and the Auditor-General’s panel of counsel.

Gregor can assist businesses with a range of workplace compliance issues. He has prosecuted health and safety related matters and undertaken significant privacy impact assessments. He championed the policy work underpinning New Zealand’s anti-money laundering legislation and has published guidance on AML compliance.

Gregor also practices as a workplace investigator. He is uniquely placed to responsibly accept instructions concerning misconduct amounting to potentially serious criminal conduct.

Gregor has an affinity for work in the health sector and acts for a number of Medical Officers of Health around the country and on professional disciplinary matters.

Gregor is also a qualified mediator and accepts instructions to undertake mediations and to otherwise help parties to reach mediated solutions.
