• Local, family-owned, and engineering-led

    DM Holdings is based in Dunedin and services the lower South Island. With more than 50 years of combined experience, we’re here to deliver safe, professional solutions for pests, trees, and vegetation.

  • Our Story

    DM Holdings was founded by Dave and Seth McPhee, who built the business from small beginnings into a trusted name across Otago. In 2023, new owners Ben and Tom brought their engineering and project management expertise to the company, strengthening its systems and operations.

    That engineering mindset now shapes everything we do, every job has a clear scope, every spray run can be GPS-tracked, and every team member knows exactly what’s expected before arriving on site.

    The business remains family-owned and locally based, with the same hands-on approach but a sharper focus on structure, efficiency, and doing the job right the first time.
