Our Team

At NK Asphalt, we employ a talented team of 18 people with two generations across four families, in both our contractors and admin staff. Several team members have worked with us for over twenty years and have passed their skills and passion in the industry on to their younger family members.

The Owner and Support Staff

Owner, Trevor Calnon has worked in the Asphalt industry since 1980 and started NK Asphalt with Les Hackett in 1989, growing it from a small independent asphalt laying company into what is accepted by even our opposition, as one of the best in the industry.

As well as overseeing the general running of NK Asphalt, Trevor is responsible for the overall running of the business and the quoting of work and has helped ensure our company is here for the long term so that we’ll be here if you need us again in the future.

In addition to Trevor, the company’s operations are run by Trevor’s son, Paul Calnon (Operations Manager) and Les Hackett’s nephew, Brad Lemmey, (Asphalt Supervisor).

Paul, who started in 1994, has worked in all aspects of the business for more than 20 years and now quotes work as well as administering the various works NK Asphalt provides, such as baseworks, kerbing, drainage and all aspects of site/job preparation.

Brad has worked his way up through every aspect of the asphalt crew at NK Asphalt and other companies.

Trevor, and his son Paul, are both available to visit the site for advice, quotations and to provide information that only comes from experience and many years in the asphalt industry.


Our biggest advantage to you, the customer, is that the people on-site, in the office, and the directors still have that old-fashioned pride in our work. Our crew are full-time wages staff and we have worked together, in some cases, for over thirty years. To ensure continuity, productivity and the best way of carrying out the job on-site, we also employ younger staff. We value our staff highly and have a very low turnover. This is how we can guarantee consistency in our jobs that other companies can only dream about.

Administration Staff

Frances Searles and Margaret Kirkman provide administration support to the team, keeping things running smoothly.

Paul Speering (OHS Manager) also plays an important role in the day to day administration and processes. He is also available to discuss and/or visit sites to plan traffic management requirements for complex projects where this needs to be considered.
