Jones said the project provided work experience where plant operators could gather practical evidence and verification of competency, which could contribute towards the completion of a number of civil construction national certificates.
It also allowed soldiers access to industry-leading subject matter experts, who were more than willing to share their knowledge.
"There will be two to three soldiers on site for a six-week rotation, which will continue until the duration of the project," Jones said.
Te Ahu a Turanga Alliance project director Tony Adams said the soldiers working on the site had quickly become an integral part of the earthworks team.
"These soldiers are highly capable professionals, so we're utilising their training and experience to benefit the construction of the highway. We've inducted 18 soldiers to date and we look forward to their ongoing contribution to this vital piece of infrastructure."
