When you start with us, you will learn that we are all brought together by the passion we have for putting the customer at the heart of everything we do.

If you’re a recent engineering graduate or have 1–2 years’ experience under your belt and you’re hungry to learn, build real capability, and make a visible impact—this could be the opportunity you’ve been waiting for. At Winstone Wallboards, our engineers work at the heart of New Zealand’s only plasterboard manufacturing operation, improving processes that keep the country building.

As a Continuous Process Improvement Engineer, based at our Christchurch site, you’ll apply your engineering skills to improve safety, reliability, efficiency, and product quality across our manufacturing operations. You’ll be supported to develop capability across areas such as:

• Health, Safety & Environment – Designing and implementing plant improvements with safety front of mind. Supporting risk assessments, audits, and safe systems of work. Helping ensure environmental compliance and best‑practice manufacturing.

Supporting and leading small‑scale capital and continuous improvement projects. Developing your expertise in process control and automation systems. Supporting plant trials, product development, and formulation changes.
• Teamwork & Systems – Working closely with manufacturing teams to solve real operational problems. Helping develop SOPs, engineering standards, and best‑practice processes.

• A genuine interest in how things work and how to make them better
• Strong analytical skills and attention to detail
• Curiosity, resilience, and a willingness to learn fast
