NCIG CEO Aaron Johansen said the company was supported by many women in business-related roles such as finance, safety, information technology, environment and human resources, however, it recognised its technical roles had relatively low female participation.

"We believe females have a lot to offer in terms of collaborative character traits and unique ways of problem solving and that's why we were looking to recruit more women into these roles," he said.

After receiving an exemption from the NSW Anti-Discrimination Board to conduct the female targeted recruitment, NCIG put the roles to market and found there were a lot of highly qualified and experienced tradeswomen from across Newcastle and the Hunter keen to join the company.

It invited a number of candidates to take part in NCIG's Technician Assessment centre, which involved team members from across the business participating to assess candidates on both role suitability and cultural fit.

The new recruits are Chloe Harris (electrical), Emma Jenkins (electrical), and Sophie McDevitt (mechanical).

Harris has most recently been working as a high voltage electrician and has extensive experience in servicing and fixing breakdowns on mining machinery fleets including haul trucks, dozers, loaders and graders.

Jenkins is experienced in performing routine and breakdown work on a wide range of coal processing equipment including conveyors, stacker reclaimers, feeders, as well as transformers, switchboards and control systems.

McDevitt has experience in preventative and corrective maintenance, pneumatics and hydraulic repairs, and fault finding on heavy diesel equipment and underground machinery.
