Several months later, the victim's mother did so and triggered an investigation.
When asked whether he told workers to use protective gear, Anderson's response was: "I'm not their mother and going to dress them every morning."
He said he did not provide full instruction to the victim on personal protective equipment such as safety glasses because "it was common sense".
PPE was too expensive and "I'm too small for that sort of ... carry on," he told a WorkSafe inspector.
Anderson's comments reflect an "outdated, unacceptable, and cavalier attitude," WorkSafe's national manager of investigation Hayden Mander said.
A young man at the start of his working life has lost sight in one eye, he said, and it was "astounding" that his employer did not understand the seriousness of the situation.
Kaikōura District Court Judge Raoul Neave ordered Anderson to pay $22,500 to the victim for emotional harm and losses.
He was unable to pay a fine and did not have insurance.
He had faced a maximum fine of $10,000 for each of the two charges faced - failing to ensure the health and safety of his workers and exposing them to risk of serious injury, and failing to report the injury.
Workers who are vulnerable because of age, inexperience, or conditions of unemployment may be less likely to question health and safety practices, or to speak up if they are unsure, WorkSafe said.
It is illegal and wrong for an employer of any size not to report an incident like this, Mander said. "No employer is exempt."
