Installing in New Zealand
Plan Your New Zealand Water Connections
Plan the installation around your building, washers and local water services. Confirm the required trades, supply protection and discharge conditions with the provider before work starts.
Authorised Trades
Confirm appropriately authorised plumbing, drainlaying and electrical trades for the work. Check the PGDB register for plumbing and drainlaying, and EWRB licence guidance for electrical work. Agree any building-consent requirements and who will arrange them.
Backflow protection
Agree separation of the potable supply and recycled-water pipework, with backflow protection suited to the site. Use MBIE’s G12 water-supply guidance and the actual water operator’s connection requirements. The laundry team and provider select reuse stages; fresh water remains where the wash programme requires it.
Trade-waste & metering set-up
Confirm discharge conditions and the billing method with your wastewater operator. Agree separate readings for fresh and reused water, plus the discharge tests required for your site. Watercare’s trade-waste guidance applies to Auckland services; the NZ water regulations guide helps prepare the wider site assessment.

FAQs
Common Installation Questions
Everything you need to know before starting your installation journey.
Will installation disrupt my operations?
Agree connection downtime and work windows with the provider before installation. Consider your shifts, spare linen and access, and plan fresh-water backup and restart checks. Confirm whether off-hours work or phased installation is practical for your site.
How long does installation actually take?
Your provider sets the schedule from the equipment, site preparation, pipework, electrical work, delivery and connection windows. Separate survey and design time from installation, testing and training, then agree a schedule that fits your laundry.
What if I don't have enough space?
Start with a complete layout covering the equipment, tanks, pipework and maintenance access. Wientjens lists 4 m² for Blue Ocean and 1.2 m² for AquaMiser equipment. Allow additional space for the proposed connections and storage, and confirm the model and location with the provider.

Can you work with my existing washing machines?
Assess your washer makes and models, inlets, drainage, controls and wash programme. Wientjens lists Blue Ocean for washer-extractors and tunnel washers, while AquaMiser and AquaBatch 3 are tunnel-washer equipment. The provider checks the selected model against your existing machines.
Source: Wientjens AquaBatch 3
What's included in the installation cost?
Ask the provider for a quote that clearly separates equipment, pipework, electrical work, labour, testing, training, documentation and aftercare. Confirm any building preparation, consent responsibilities and exclusions before agreeing the project.
What happens if something goes wrong during installation?
Agree site contacts and the issue-reporting process before work starts, including stop procedures, fresh-water backup and checks before washing restarts. Get written responsibilities and installation-warranty terms from the provider.
How much training do my staff need?
Agree training for the selected equipment and your operator and maintenance roles. Cover starting and stopping the system, controls and readings, water and linen checks, maintenance and how to get help. Training time depends on the equipment and your team’s experience.
