Quinton Penniall 
Environmental Engineering Manager, Central Otago District Council 
IPWEA NZ Otago/Southland Branch Chair

E: Quinton Penniall


Quinton was appointed to the IPWEA NZ Board in September 2021.

Currently living in Cromwell with my wife and our two dogs, I am passionate about public infrastructure - it is instrumental in helping communities prosper and thrive now and into the future, mindful that it’s my future too.

I have understood IPWEA’s value since I presented as a graduate at an Otago Southland Branch meeting. I have been an advocate for the network throughout my career, including in my current role as Environmental Engineering Manager at Central Otago District Council.

It is in that context I seek your support to represent you as Otago Southland Branch Chair.

I will bring a combination of youth, passion and pragmatism. My private and public sector experience has taught me successful relationships will be critical to advancing our objectives and effectively participate during a time of unprecedented change.

As we enter the most significant reforms in a generation my focus will be on enabling all members (young and less young!) to share knowledge and engage, ensuring we keep challenging ourselves and the industry we’re responsible for as it transforms. We will celebrate successes and create a safe space to talk about mistakes too, because that learning is a major component in getting things right.
