A security guard says if a young man killed on the job had been better trained he would have known to stay in his car and call for help.
Charanpreet Dhaliwal died after being bashed on the head just hours into his first shift on an Auckland building site in November 2011.
Bryce Winstone told a North Shore inquest into Mr Dhaliwal's death the 22-year-old was not properly equipped or trained for the job.
He said Mr Dhaliwal should have had a radio telephone rather than a cellphone when he was confronted by four men on the night he was killed.
He said the violence was extreme and rapid but he would still have had time to push the panic button.
Mr Winstone said Mr Dhaliwal's employer, CNE Security's Cherag Elavia, lacked knowledge about the importance of radio telephones and routine welfare checks on guards.
But Mr Elavia said he had not failed to make sure the guard was adequately trained.
Yesterday, a former employer from FIRST Security told the inquest Mr Dhaliwal had been trained in crowd control, and not as a static guard.
But Mr Elavia, who hired Mr Dhaliwal on the night of his death, said there was no difference.
Mr Elavia said he was assured by Mr Dhaliwal he had been adequately trained when he was asked to work for the first time that night.
He told the inquest there should never have been a confrontation, and that Mr Dhaliwal should have known not to approach the four men who intruded on the site.
"With due respect, common sense would prevail - that you'd sit in your car, get away from them.
"I would have stayed in the car, if it was me. Yes - I would have made sure the car was locked as well."
Mr Elavia said Mr Dhaliwal should have reported the incident and remained in his car.
CNE Security was cleared in 2013 of failing to provide a safe workplace for Mr Dhaliwal.
