Maru said that this denial of funding was a criminal abuse of authority by the Treasury and Finance ministers - for political purposes - would hurt a lot of people.
Maru was referring to provincial services improvement program (PSIP) and district services improvement program (DSIP) funds.
"People in remote and rural communities around the country are suffering because this government is using DSIP and PSIP as a way to apply political pressure. These funds are specifically allocated to deliver services to our grassroots people and the funding is particularly important when government does not perform its primary functions properly - as is happening now.
"There has never been a more important time for districts and provinces to be able to directly fund the urgent needs of our people who are already suffering because of the national economic collapse."
Maru said the government's abuse of power in not releasing the funding was driven by desperation politics.
"There is a clear threat being conveyed to MPs that if they did not toe the line and vote with [Prime Minister James] Marape, they would lose DSIP or PSIP funding. As such, opposition MPs have only received a fraction of allocated DSIP and PSIP funds as the government plays politics with people's lives.
"Never before has a government played such nasty politics over these funds, and this has very direct and harmful consequences for our people, particularly in remote areas."
