I was admitted in 2004. I have worked across a range of litigation disciplines in a national litigation firm and as a Crown Prosecutor. I joined the bar in 2015 and continue to enjoy a varied practice.

The work I like to do 

My main litigation interests are general civil and commercial, professional negligence and discipline, employment law, and regulatory/criminal matters (particularly health and safety and transport/aviation). I have conducted dozens of trials and appeals as lead counsel across all of these jurisdictions.

The clients that I work with cover a full spectrum, from one off assistance for individuals and SMEs, through to ongoing work with councils, listed companies and large insurers.

I regularly undertake independent work as amicus curiae, counsel assisting and standby counsel in civil, criminal and Coroners courts.

As an investigator I conduct independent inquiries and investigations in workplace and governance situations.

I am available to take instructions across New Zealand.
