We are proud to partner with the following organisations:


Aluplast Logo.svg





We partner with German-based Aluplast GmbH for uPVC profile systems. They are world-leaders in the field and focus solely on uPVC for window and door systems. Their products are used around the globe. The raw materials used by Aluplast for window profiles are based on a calcium-zinc chemical stabiliser that is strictly lead-free. With this eco-friendly stabiliser and Aluplast’s involvement in “VINYL 2010”, that among other things dictates the use of recycled materials in their plastic profiles, Aluplast offers window systems that can be fabricated and recycled in an ecologically sound way. www.aluplast.net

sopers macindoe logo

In April 2013 two leading New Zealand builders’ hardware specialists’ suppliers, Sopers NZ and Wilson Macindoe, joined forces to become Sopers Macindoe and Banks Limited Partnership. Both parties brought different strengths to the partnership combining the strong trade, retail and web presence from Sopers NZ with the commercial project management and installation expertise of Wilson and Macindoe. Prior to the merger both entities had traded successfully in the NZ market for over 65 years. 100 staff NZ-wide. https://www.sopersmac.co.nz


Superhome Logo

The SUPERHOME movement is creating awareness for homeowners, builders and designers, triggering behavioural change in decision making on designing and building superior homes. The current building code describes the lowest possible building standards that are legally permitted across New Zealand. BRANZ research shows that the building code is universally mistakenly used as the target quality standard rather than a legal minimum. NK Windows is proud to be one of five Primary Partners of the SUPERHOME movement.
