The two bodies have agreed to discuss ways to avoid such problems in the future after signing a memorandum of understanding.
The MOU was signed by the Minister of MIPU, Jay Ngwele and Mayor of Port Vila, Eric Puyo-Festa, yesterday.
Recent rainfall flooded some roads in Port Vila due to improper drainage. Flooding can wash out roads and damage vehicles.
Prior the MOU signing yesterday, Minister Ngwele visited a flood affected area at Anambrou.
