Tex has a B.Com from the University of Auckland and started his career in banking and stockbroking in NZ. He qualified as a corporate treasurer in London and is a member of the ACT in the UK by qualification. Tex has completed the NYC marathon 15 times and is a parent to a young sailor and fishing guru.

He worked in investment research in Africa, the Middle East, and Japan, and in the US in equity capital markets. He pioneered investment into African mobile phone companies in the 1990s after publishing several financial journals about African stock markets. He founded the NZ 2degrees mobile phone business in 2001, a business in which he worked and held a shareholding until 2016. It took Tex a decade to get 2degrees operational—a business he originally thought would take six months to get going.

Tex has a long list of original published research reports ranging from "The Business Case for Offshore Currency Loans for NZ Corporates," "Spot the Risk: A Guide to Japanese OTC Options," and "A Guide to African Stock Markets," to "A Guide for NZX Top 50 NZ Equity Issuers in the US," "A Guide to Telecommunications Competition in NZ," and "A Guide to the Banking Cartel Forum in NZ." He has also published explanations of why NZ builds social houses at $8,000 per sqm when the international benchmark is $900 per sqm, why NZ has the world’s most profitable supermarkets, the history of thought diversity in NZ boardrooms, and the core three questions to ask in meetings.

Monopoly Watch is a public policy group which he founded in 2016 to advance Kiwi consumers' welfare in capital-intensive industries. His motivation to set up Monopoly Watch was to thank the customers who helped him secure a victory for the 2degrees business. Monopoly Watch has anchored research in telecommunications, supermarkets, building materials, banking, fuel distribution, insurance, and aviation.
