The contributions was given by national employees of Higaturu Oil Palm Limited (HOPL).
The 6,900 workers contributed K20 each with some giving more towards the funeral arrangements.
The employees include those at HOPL, POPGA, OPIC and growers from Mamba down to Embi Estate.
One food truck will be given to each of the 13 victims.
Spokesman for the employees Ezekiel Baraha stressed that they were not there to represent any organization, but as fellow Papua New Guineans expressing their condolences in typical Melanesian way.
