Meet our Board

Andrew Johnston

Tumuaki Tauiwi (Co-Chair)

Ko Andrew Johnston tōku ingoa. I was born in Ōtautahi and have spent my working life in Te Waipounamu. Growing up on an orchard in Ouruhia shaped my appreciation for resilience, sustainability, and the power of community.

This foundation led me to study agriculture at Massey University, where I developed a deep understanding of how people, environments, and systems connect.

I feel a strong calling to serve and contribute to the wellbeing of our communities. I am passionate about ensuring that people have the support they need to thrive, particularly in times of change and challenge.

Outside of my governance roles, I enjoy tramping, open-water swimming, and immersing myself in a good book.

Te Teira Pitama

“Mō tātou, ā, mō kā uri ā muri ake nei.” For us and our children after us.

I’m really excited to be joining the Presbyterian Support Upper South Island Board.

I was raised in Ōtautahi and whakapapa to Ngāi Tahu and Ngāti Kahungunu. I attended Christchurch Boys’ High School before completing a Bachelor of Arts in Māori and Indigenous Studies and a Bachelor of Laws at the University of Waikato. I now work as a solicitor in the commercial and corporate team at Simpson Grierson.

I was raised in a strong whānau of kaimahi in the health sector, which has shaped my appreciation for care, service, and the importance of supporting people and whānau in our communities. My background is in commercial law and governance, and I have a particular interest in contributing to organisations that strengthen community resilience and enhance the mana of whānau.

I am passionate about what PSUSI stands for and the opportunities it strives to create for our communities to be safe, resilient and connected. I am proud to be part of an organisation that reflects these values in its mahi.

I live in Ōtautahi with my wife and our three children, and I look forward to getting to know and working alongside everyone involved in the organisation.
