Commercial Water Treatment for Auckland, Wellington & Central North Island

Welcome To Membrane Solutions NZ Ltd

At Membrane Solutions NZ Ltd, we specialize in high-performance RO, UF, and Nanofiltration systems — engineered to match your unique water quality needs.

Our Membrane Solutions

At Membrane Solutions NZ Ltd, we provide high-performance water filtration membranes that meet the demands of diverse applications — from household systems to industrial and municipal plants. Our product range is carefully selected for quality, reliability, and efficiency.

Reverse Osmosis (RO) Membranes

For ultra-pure water in residential, commercial, and lab applications.

Ultrafiltration (UF) Membranes

Great for removing suspended solids, bacteria, and viruses.

EDI Water Polishing Modules

Electro De-Ionization is currently the most advanced technology for ion-exchange.

CSSD & High-Purity Water

CSSD, Endotoxin Control & RO Technical Consultancy

Membrane Solutions NZ provides independent technical review, fault-finding and system-design support for CSSD and other critical high-purity water applications. We assess the complete water path: source water, pretreatment, reverse osmosis performance, final barriers, storage and distribution, sanitisation, instrumentation, sampling points and the interfaces with washers, sterilisers and laboratory equipment.

Engage us as a consultant to appraise an existing installation, identify performance or bacterial and endotoxin-control shortfalls, prepare a prioritised corrective-action plan, or specify a new RO system and process flow where suitable treatment is not yet installed.

Our current field involvement includes three hospital sites and four laboratory environments across New Zealand. This includes confidential review work on complex multi-party installations where the treatment arrangement may be contributing to bacterial loading. Our role is evidence-based: establish what is happening, identify the risks and work with the facility and relevant specialists toward a practical solution.

Custom Filtration Design

Custom Solutions, Built Around Your Water Report

No two water sources are the same. That’s why we tailor every membrane setup to your actual water report. Our process ensures each system is optimized for your exact needs — whether you’re filtering rainwater, groundwater, or industrial waste.

How it Works:

🤝 R&D Partnerships

R&D Collaborations & Pilot Projects


If your facility is facing a complex or unconventional water issue, we offer a collaborative opportunity to design, test, and validate a solution together. Through our pilot plant co-investment program, we’ll share the costs and efforts to install a compact pilot system (with a capacity of 1–2 m³/hr) directly at your site.

This hands-on approach allows us to rigorously test the solution under real operating conditions, ensuring it meets both performance and compliance expectations. Once the pilot phase is complete, you retain the system at no extra cost, while we gain valuable data and insights to further refine our technologies.

Membrane Solutions NZ Ltd

At Membrane Solutions NZ Ltd, we are dedicated to advancing membrane filtration technology to improve water quality across New Zealand’s industrial, agricultural, and domestic sectors. While membrane filtration is already widely adopted overseas, New Zealand has only begun to tap into its potential. We believe the time is right—thanks to evolving industry demand and more competitive market conditions—for membrane systems to become a practical and affordable solution for even the most complex water challenges.

New Zealand’s water sources are uniquely diverse and often present filtration issues that traditional methods struggle to resolve. That’s where membrane technology excels. We view it not only as a powerful tool today, but as the future of water treatment—continually evolving, adaptable, and capable of delivering exceptional results in sustainability and efficiency.

What We Offer:

At Membrane Solutions NZ Ltd, we don’t just sell systems—we engineer outcomes. Our approach is driven by science, shaped by experience, and tailored to each unique environment.

High-Purity Filtration for Demanding Applications

Reverse Osmosis (RO) Membranes

Our Reverse Osmosis (RO) membranes are engineered to deliver the highest level of water purification by removing up to 99% of dissolved salts, heavy metals, bacteria, viruses, and other microscopic contaminants. These membranes are ideal for industries and environments where ultra-clean water is essential—such as food processing, pharmaceuticals, agriculture, and potable water supply.

Membrane Solutions NZ Ltd
Reliable Protection with High-Performance Filtration

Ultrafiltration (UF) Membranes

Ultrafiltration (UF) membranes are designed to remove suspended solids, bacteria, viruses, and other harmful microorganisms while allowing essential minerals to pass through. Operating under lower pressure than reverse osmosis systems, UF provides a cost-effective and energy-efficient solution for a wide range of applications—from municipal water treatment to commercial and industrial pre-filtration.

Membrane Solutions NZ Ltd
Selective Filtration for Targeted Water Treatment

Nanofiltration (NF) Membranes

Nanofiltration (NF) membranes bridge the gap between ultrafiltration and reverse osmosis, offering selective separation that allows beneficial minerals to pass through while effectively removing larger molecules and harmful contaminants. NF is ideal for applications requiring partial softening, organic matter reduction, and selective ion removal without the intensity of full desalination.
