Police have confirmed a 20-year-old learner driver was behind the wheel of a truck operated by NBN Co, which crushed the 57-year-old on Friday morning.

Emergency services were called to Seaview Street at around 11.35am to find Mr Gouveia, of Lake Heights, with serious head injuries.

Police were first on the scene and applied CPR for several minutes, however Mr Gouveia was pronounced dead shortly after.

Relieving Lake Illawarra Commander Acting Superintendent Andrew Koutsoufis said Mr Gouveia had been trapped between a stationary truck belonging to a concreting company doing work at a nearby house and a second truck operated by NBN Co.

Police said Mr Gouveia, working for the concreting company, had been collecting an item from the back of the first truck when the unaccompanied learner driver entered the NBN truck, parked immediately behind.

"It was a tragic incident for the fellow: he had moved between two trucks; one lurched forward and trapped him," Supt Koutsoufis said.

"It appears at this stage the NBN truck had lurched forward."

NBN Co contractor Silcar was laying topsoil in the area at the time.

Seaview Street was closed for several hours while the Crash Investigation Unit and WorkCover investigated. Police are still running an inquiry.

Mr Gouveia is survived by wife Pina and two children, Peter and Elise.

He was involved with the Port Kembla Football Club for decades, including more than 10 years as a committee member.

A Silcar spokesperson extended their sympathies to the Mr Gouveia's family and friends and said the company was co-operating with inquiries.

"Support is being extended to the man's family and counselling is being provided to workers to assist them through this very difficult period," the spokesperson said.

The NBN truck's driver was taken to hospital for mandatory testing.

The accident ended a difficult week for the National Broadband Network, already hampered by asbestos concerns.

The incident occurred as Telstra stopped all pit remediation works across the country due to several alleged incidents of mishandling asbestos.

A spokesman said work would not continue on pit remediation until Telstra was "confident processes are of the highest order". All contractors and sub-contractors will be required to complete further training on working with, removing, transporting and disposing of asbestos.

Telstra will also review the mandatory training program all contractors must implement before they are approved to work on Telstra pits.

Consultant PriceWaterhouseCoopers will work as the company's independent advisers to help review processes.

The stop-work on pit remediation affects the Kiama and Jamberoo second release sites, however an NBN Co spokeswoman said other work could continue.
