From the ground up

We're specialists in our field, solving complex problems and delivering successful outcomes.

In the late 1960s, Brian Hannah and his wife, Dorothy, had a small agricultural contracting business, based in Tuakau. The Spiral Drillers journey began in 1971 when Brian, ever the entrepreneur, saw an opportunity to diversify and expand, starting with drilling and later incorporating piling works. Over the years as Brian and Dorothy’s young family grew, so did their business, with a culture of innovation becoming a key factor in the company’s continued success.

In 2010, Jon Faber and Andy Hannah assumed the roles of co-owners at Spiral, with the aim of further enhancing the business and establishing it as the premier specialist piling company in New Zealand. The company’s progressive expansion persisted, focusing on large commercial projects and technically complex jobs, that demanded specialist expertise. As a result, project opportunities expanded beyond the greater Auckland and Waikato regions, which had been the company’s previous service areas.

Spiral took another significant step forward in 2018 by acquiring Hauraki Piling. The strategic acquisition of Hauraki, an established company since 1990, bought about improved economies of scale and granted access to a broader range of resources along with expertise in the infrastructure sector. In 2020 we further expanded our transportation division to include Heavy Haulage, enabling us to efficiently transport our own large plant and machinery while also serving external customers.

In September 2023, we moved our Auckland operations and people into a new purpose-built facility in Drury South. We operate across the civil infrastructure, commercial, and residential sectors, offering heavy haulage, transportation and plant and equipment hire services. Our capacity and capabilities continue to expand, allowing us to deliver reliable, sustainable and cost-effective solutions throughout New Zealand.
