Perfect for installers, HVAC professionals, builders, renovators, workshops, and homeowners across New Zealand

If you require efficient airflow management for heating, cooling, exhaust extraction, or ventilation systems, Ducting Pipe NZ provides the essential conduit for moving air cleanly and effectively. Designed for residential, commercial, and industrial applications throughout New Zealand, this ducting pipe supports HVAC installations, bathroom and kitchen ventilation, workshop dust extraction, and indoor air quality improvement. Whether you’re working on a new build in Auckland, a renovation in Christchurch, or mechanical installation in Wellington, this ducting pipe delivers dependable performance tailored to NZ standards.

Description – Ducting Pipe

The Ducting Pipe NZ is a cylindrical conduit engineered to channel air between fans, vents, grilles, and exhaust points within mechanical ventilation and HVAC systems. It forms the backbone of air distribution networks, helping move conditioned or extracted air while minimising resistance, noise, and energy loss.

Manufactured from materials suited to the application environment, ducting pipe options may include:

• Galvanised Steel: Heavy-duty and corrosion-resistant, ideal for long-term HVAC installations in residential, commercial, and industrial settings.
  
• Aluminium: Lightweight and naturally corrosion-resistant, suitable for roof-space ventilation, ceiling cavities, and external duct runs.
  
• PVC or Rigid Plastic: Economical and lightweight for bathroom, laundry, and kitchen exhaust ducting where moisture resistance is prioritized.
  
• Flexible Ducting (Reinforced): Flexible polymer or foil ducts with internal spring wire allow routing around obstacles, connecting fans to fixed ducts, or reaching confined spaces.
  

Ducting pipe supports the movement of warm or cool air, extraction of moisture and odours, and distribution of fresh air throughout buildings. In HVAC systems, properly sized ducts help maintain balanced airflow, reduce load on fans and heaters, and improve energy efficiency.

Proper selection of duct diameter and layout affects system performance. Larger diameter ducts support higher airflow with reduced pressure drop, while smaller ducts may cause increased fan workload and noise.

Connection methods include slip-fit joints with clamps, sealed couplings with gaskets, or flanged connections for one-piece assemblies. Sealing joints with appropriate tape or mastic enhances airtightness and reduces leakage.

Ducting pipe is widely used for:

• HVAC supply and return air distribution
  
• Bathroom and laundry exhaust systems
  
• Kitchen rangehood ducting
  
• Workshop dust extraction systems
  
• Commercial ventilation applications
  
• Basement and attic air movement
  
• Fresh air intake networks
  
• Roof and cavity ventilation
  

In New Zealand’s varied climate, effective ducting contributes to indoor air quality by removing excess humidity, odours, and airborne contaminants. This is vital for residential comfort, commercial productivity, and condensation control in enclosed spaces.

Installation considerations include routing to avoid sharp bends and abrupt transitions that increase airflow resistance, ensuring proper support and bracing, and protecting ducts with insulation where temperature control or condensation prevention is needed.

Maintenance involves periodic inspection for dust buildup, blockages, or loose connections. Metal ducts can be cleaned using standard HVAC cleaning methods, while flexible ducts should be checked for kinks or compression that restrict airflow.
