The investigation into the crash is ongoing, and further charges are possible.
James Trevelyan, managing director Trevelyan Pack and Cool Ltd, said Trevelyans lost two "valuable members of our Vanuatu RSE family" this morning.
"They were tragically taken in a motor vehicle accident on No 1 Rd, Te Puke.
"We are currently supporting the remaining team in this trying time and our thoughts and sympathies are with the extended families back in Vanuatu."
Trevelyan said staff were supporting their Vanuatu employees and were feeding about 60 people from their campsite.
He said staff, including himself, had been to visit one of the victims who was still in Tauranga Hospital.
