Patricia Canavan

My path to finance has come via sales and marketing positions in multinational companies in Europe, managing a service company in Ireland and then gaining my “kiwi experience” at PwC, in Auckland.

I’ve been with pH7 since 2015 and am one of the owners of the business. I’ve witnessed the company growing its product and service offering, while strengthening its market position and overall HAZCHEM expertise.  I love living in NZ, raising three cherubs and getting outdoors as much as I can.

I am originally from San Diego California and relocated with my family to New Zealand in 2014. My family loves to travel and after a holiday in New Zealand our daughter decided she wanted to get her Master’s Degree in Winemaking here.   I started my career in law and have expanded my experience to real estate, cleanroom protocol training and now working with pH7.

I am an Associate Member of NZOHS and am a Commit2Fit Certified Respiratory Fit Tester.  I have also completed The Educhem Management Course with Environmental Protection Authority Notices and Health and Safety at Work Regulations, have a Certificate in Mould Hazard Awareness Training from MHA, Compliantly Managing Hazardous Substances and W507 – Health Effects of Hazardous Substances.  I specialise in site risk assessments and travel the country working with businesses that handle hazardous substances.
