“Ngā tangata Picts o Kōtirana, ngā tūpuna o tōku matua. Nō North Warwickshire, Ingarangi ngā tūpuna o tōku whaea. Nō Yorkshire, Ingarangi ahau. E noho ahau ki Piha, ki te Wao nui a Tiriwa, ki te hauāuru o Tāmaki Makaurau. Ko Kataraina Dewar tōku ingoa.

My father’s ancestors descend from the Picts of Scotland and my mother’s ancestors are from North Warwickshire, England. I am from Yorkshire and I now live at Piha in the Waitakere Ranges, West Auckland. My name is Katherine Dewar.”

A Fellow of the UK-based Chartered Institute of Marketing and an award winning international marketer, Kath joined the Sustainable Business Network in Aotearoa NZ in 2003.  This began the journey to meld Kath’s personal values with her professional practice, leading to the creation of the GoodSense team in 2010.

She served as a judge for the Mindful Money ethical investment awards from 2021 to 2023, and for the Sustainable Business Network Awards in  2017 – 2020 and 2010 – 2012.  Kath was a finalist in the Sustainability Superstar Category of the Sustainable Business Network Awards in 2023, and in 2021 GoodSense were finalists in the same Awards with client Outside The Box.
