We’ve been working with the New Zealand dairy processing industry for 30 years. We understand what’s required and we know what’s at stake.
Avoid budget blowouts

All project costing, materials and services contractor management and overall financial control of each project is overseen at senior level by Serena Roberts, company director and CA.

Sound financial control
Minimise delays and disruptions

Off-site manufacturing, modular design approach and smart tech tools such as PointCloud allow us to engineer solutions while production continues. Our own hygienic steel fabrication capability gives us tight control over manufacturing timelines.

Production continuity
Get the optimal solution

Cortek is an independent, New Zealand owned company with a high level of transparency and accountability. While we work with the same services and equipment providers as others in our industry, we are free to pick those that best serve our clients' needs.

If there’s a better way, we’ll find it.
