The Solomon Islands Leadership Code Commission has warned public servants it will investigate those with unexplained wealth.
The chairman, Solomon Kalu, says his investigators will probe some public servants who own properties that are beyond their incomes.
Mr Kalu says people who know public servants with unexplained wealth can report them to the commission.
He says the call has been made amid claims some public servants are enriching themselves through dishonest allocations of government contracts.
Mr Kalu says corruption in high office can only be weeded out if people co-operate with the Leadership Code Commission.
