Our Relationship

Due to the rapid increase in new home builds in NZ, Castle struggled with the demand for ground chairs and asked Waipak to help. Here at Waipak we now manufacture the G50/65mm and G85/100mm bar chairs. Along side this, we have been working on an exciting new recycling project! All reject and used PET plastic bottles are re-ground and re-processed back into our machines to be turned into bar chairs. This process ‘closes the loop’ turning single use bottles into something permanent. Follow us on our LinkedIn and Facebook pages to keep up to date with our latest sustainability work!
