Transparency International in Vanuatu says there should be an immediate inquiry into alleged misconduct and corruption in the Lands Department.
The watchdog's president, Marie-Noelle Ferrieux-Patterson, says she welcomes a report by the Ministry's former Director-General but it's not much use if policies aren't changed or other action taken to stamp out the problem.
Ms Ferrieux-Patterson says the report should be made public and followed up.
"It's one man writing it, the Director-General, so if there is any dispute about these facts then there should be a Commission of Inquiry being appointed to actually look deeply, legally into these matters and deciding upon it."
Ms Ferrieux-Patterson says the office of the Ombudsman has done nothing to look into such allegations over the years.
