WHO WE ARE

Mitchell Daysh is a specialist environmental and planning consultancy, trusted to navigate New Zealand’s most complex resource management challenges.

With a team of more than 45 consultants across eight regions, we combine deep technical expertise with broad industry experience. Our reputation is built on delivering clear, practical solutions that endure.

At the heart of our business is a simple belief: our people are our greatest asset. We foster a supportive, high-performing environment where individuals can excel, collaborate and grow.

OUR APPROACH

We are solutions-focused, working closely with clients, stakeholders, and communities to bring absolute clarity to the issues that matter.

Collaboration underpins how we work - operating as one team - bringing together the right expertise for every project. Alongside our New Zealand team, we draw on the wider EMM Global network across Australia and Canada and partner with trusted specialists to ensure the best capability is always applied. We are committed to delivering outstanding client service, built on strong relationships and underpinned by quality, technical excellence, and effective facilitation.

OUR HISTORY

Since inception, Mitchell Daysh has had an uncompromising focus on quality and technical excellence. Our growth has been driven by client needs and the ambition of our people.

A defining moment in our history was the merger of Mitchell Partnerships and Environmental Management Services Limited in 2016. Our founders remain actively involved, alongside a team with decades of experience across some of New Zealand’s most significant and complex projects.

Today, our breadth of expertise and depth of capability continue to strengthen our reputation as a leading environmental consultancy.
