About
Spence Solutions Limited is a New Zealand-based consultancy drawing on over 10 years of industry experience in the water treatment sector. Established in 2025, we were founded with a clear purpose: to help streamline project delivery, improve project outcomes, and elevate client satisfaction across water and wastewater infrastructure.
