"For the past 30 years Yunca’s work with NZAS has provided us with a platform to build deep expertise and capability within the Yunca Group. This experience has enabled us to successfully tender and win international contracts from other aluminium smelters including Boyne Smelters, Bell Bay Aluminium, Tomago Aluminium, Dubal and most recently Trimet in Germany.
The innovative aluminium smelting technology that is proudly engineered in New Zealand can absolutely be attributed to having NZAS on our doorstep. This world-class industrial asset is not only a major benefit for the community, it also supports local businesses to help propel them to the next level."
Karyna Young, CEO, Yunca Group
"NZAS engaged Callaghan Innovation’s experts on an R&D project to improve how high quality aluminium is manufactured in New Zealand. This process involves electrolysis in hundreds of reduction cells, of which cathode blocks are a major component of the reduction cells structure. Sometimes when a cathode block fails, it can shut down a reduction cell which can lead to significant expense and down time. NZAS were keen to work with our engineers to come up with a solution.
Callaghan Innovation’s engineers developed a prototype method to screen cathodes for defects before incorporating them into cells. The novel measurement technique was compared to conventional non-destructive testing methods and found to be more effective. This is a great example of successful collaboration between industry and government leading to better innovation outcomes. Our team greatly enjoyed working with the NZAS team on this project."
Robert Holt, Joint Team Leader of Electrical Engineering at Callaghan Innovation
"EIS began operating with five employees in 1995 on the back of a major upgrade at NZAS. Since then EIS has grown to be a 65-employee company and the ongoing relationship with NZAS has been instrumental in achieving that.
EIS is now looking at export opportunities and is currently working with engineering consultants from Callaghan Innovation to produce a prototype robotic anode cleaner for the global smelting industry. Having a working and supportive smelter such as NZAS on our doorstep helps us to be highly confident about our future."
Dean Addie, CEO, EIS
