Our team

Ganesh took up the position of Chair of the Productivity Commission in December 2020, after 22 years at the consultancy Business and Economics Research Limited (BERL). His work at BERL covered a broad range of projects, with a highlight being his work in strengthening relationships with Māori entities and organisations and building an understanding of te ōhanga Māori.

Prior to BERL, Ganesh acted as primary caregiver to his pre-school children while also employed as part-time lecturer at Victoria University. Before children, Ganesh managed to explore some parts of the world – including working in England as a researcher at the House of Commons gaining experience with IMF and OECD economic models. On his way home to Aotearoa he spent several months visiting family and ancestral lands across India.

Ganesh is a first-generation New Zealander, born, bred, and educated in Te Whanganui a Tara and his interest in economics originally emanated from his love of numbers, which in turn arose out of his passion for cricket. Ganesh believes economics is fundamentally about people and is best reflected in our collective role as kaitiaki o taonga.
