Hansen Products (NZ) Limited are justifiably proud to be certified to ISO9001:2015 by Telarc Certifying Authority. ISO 9001:2015 is a Quality Management System which aids to increase the  efficiency and effectiveness of any organisation, to manage the processes and activities used to  eliminate risk to the customer and to ensure that its products and service conform to customer  requirements, thus ensuring customer satisfaction.

The ISO 9001 definition of “quality” refers to all  the features of a suppliers product and service, which are required by the customer. As part of ISO Certification, a fully documented quality system must be in place which is audited by  an approved accreditation body at planned intervals (usually every 6 months). These audits ensure  that the system is being implemented and followed. Every 3 years a recertification audit is conducted. 

Internally our Process covers internal audits of the system. Inspections have been implemented at  the following stages of manufacture; goods inwards, first off, in process, final, and customer return  analysis. Non-conformances are checked to ensure corrective actions are taken and are the actions  effective. The system covers training, that all processing is fully documented, that work instructions  are available for all tasks, that all documentation is controlled, and customer requirements are clear. 

We are certified for the design, manufacture, assembly, packaging, distribution and marketing of our  products.

The WaterMark™ Certification Scheme is a certification scheme for plumbing and drainage products  to ensure that plumbing and drainage materials and products are fit for purpose and appropriately  authorized for use in plumbing installations. It also provides a uniform national approach to plumbing  product approvals. The plumbing industry in Australia & New Zealand supports the use of the  WaterMark™ which, when used properly, is an excellent way of helping consumers be confident  about the quality of the plumbing product to which it is applied. Material and product failures in  plumbing systems can cause contamination of the water system and be a public health concern.  Under the Scheme, Hansen Easy Fit Compression Fittings & Rapidflo & Sloflo Rain Relief Valves  carry the WaterMark approval and are accepted for use in all Australian states and territories &  throughout New Zealand - subject to correct installation practices in accordance with AS/NZS 3500  and any local deviations. 

The procedures and technical requirements of this scheme are identified in:  
AS 5200.000-2006 Technical specification for plumbing and drainage products - Procedures for  certification of plumbing and drainage products.
