Ron Mansfield

Ron has been a criminal litigator for 25 years. He has practised as a barrister sole since 2000 and specialises in providing clients with effective legal advice and representation in any criminal proceeding. He regularly appears in a full range of criminal courts including Specialist Tribunal Courts, Coroner’s Court, District Court, High Court, Court of Appeal and the Supreme Court.

Ron is a senior criminal trial and appellate advocate. He has developed a busy and well respected practice with a significant national profile. His expertise is particularly recognised in defending clients against drug prosecutions and related civil proceedings. Ron effectively challenges the legality of any search and other admissibility issues arising from Police misconduct, including breaches of the New Zealand Bill of Rights Act.

Ron is also routinely engaged by clients in defending serious violence – murder, manslaughter & grievous bodily harm (GBH) – rape, high level fraud & regulatory crimes. However, he is prepared to act for any client in defending a matter of significance to them and will do so with equal focus. Other matters have involved serious traffic crimes, medico-legal prosecutions, military & court martial cases, sporting & drug body proceedings and defamation.

Ron has developed a strong and dedicated legal support team which is available to work with clients.  The team includes barristers, research and briefing clerks, interpreters and private investigators (including those fluent in Mandarin and Cantonese).

Ron is generally only available for private instruction. However, he is legal aid approved for all categories in criminal proceedings but, due to demand, he will only accept instruction for serious cases falling within categories 3 and 4 and only on a preferred counsel basis.
