Reflecting on a remarkable year of craftsmanship at Portman Stone

At Portman Stone, every project begins long before installation day. It begins in our Christchurch-based factory, where precision, craftsmanship, and investment in the latest technology come together to create worktops that are designed to last.

Over the past year, we’ve continued to evolve our production capabilities, ensuring we deliver the highest standard of finish across every project. A key part of this has been the introduction of our new Donatoni CNC saw — a significant investment that enables us to cut stone with exceptional accuracy and efficiency. Combined with our digital laser templating process, this technology ensures that every worktop is manufactured to exact specifications, reducing margin for error and delivering consistently high-quality results.

While technology plays a vital role, it’s the people behind the process that truly define what we do. As a family-run business, Portman Stone has been built on a foundation of hands-on experience, strong values, and a genuine passion for the industry. This approach continues to shape how we operate today, from the factory floor through to customer service.

We are also proud to support other local businesses wherever possible. From the signwriting on our growing fleet of vans, carried out by Extreme Signs, to the recent addition of new vehicles supplied by Keith Motors, working with trusted local partners is a key part of how we run our business. These relationships not only support the local economy but also ensure we maintain the same level of quality and reliability across every aspect of our brand.

Our expanding fleet reflects the continued growth of the company and our commitment to delivering a seamless service — from initial enquiry through to final installation. With dedicated teams handling templating, fabrication, and fitting, we ensure each stage of the process is carefully managed and executed to the highest standard.

As we continue to grow, our focus remains the same: combining precision craftsmanship with honest, transparent service. Whether working on a single residential kitchen or a large-scale development, we approach every project with the same attention to detail and commitment to quality.
