Best in Dust and Fume Filtration | NZ Duct + Flex

NZ Duct & Flex offers the widest range of ducting, fans, filters and fume arms to the NZ Market. View our range online now.

The majority of our products are held in stock in Auckland and are available for collection or dispatch the same day as you order. We stock and can install complete systems using components that are widely available globally: they are tried and tested solutions – not ‘one offs’ designed for a single customer.

This efficiency allows us to be competitive and draw on the engineering experience of 3 major global suppliers with experience of thousands of industrial extraction solutions. Originally Australian owned, we became a private NZ owned company in 2009. Since then NZ Duct & Flex has grown from its product base of duct and flexible duct, to offer the largest range of dust and fume products available in this market.

“With my own Danish heritage I naturally was impressed with the European quality of the LIPLOCK® system offered. The fact that the install team had access to a warehouse full of stock meant any changes were accommodated easily. Ours was a complete new install but machines were moved from their original planned positions, but the guys were professional about the changes. Everything looks really good which is important as I deal with designers and architects. I am planning changes in the future and the whole filtration system fitted was designed by NZ Duct+Flex to deal with this, saving me money.”

KIM LEWIS, Managing Director

“From my initial request for a brochure right through to the finished install, this company provided outstanding service. The staff of NZ Duct+Flex are accommodating, helpful and pleasant to deal with. I highly recommend NZ Duct+ Flex to anyone seeking a ducting solution.”

RONNIE MOFFAT, Property Manager

“The Technology Department at our school thought Neal and the team were tremendous when they installed our new Modular filter. Despite several last minute changes, they got on with the job and made it very easy for us, explaining always why they were doing things the way they were, for our long term benefit. Before they left they gave us all the training we needed – all we need now is more collection bags!”
