"It's a rush against time to get water trucks organised for those areas so that we prevent a second disaster, which is a diarrhoea outbreak," he said.
The extent of damage to Port Vila's water infrastructure remains unclear, with repair timelines still uncertain.
Aid agencies have also noted challenges around official casualty numbers, as they believe not all have been transported to hospitals and some injured residents remain trapped or are avoiding the severely damaged Vila Central Hospital, the main medical facility.
Around 1000 people are estimated to have been displaced, according to the United Nations.
Relief efforts face significant challenges due to blocked roads, traffic congestion and limited communication networks.
Forecasted rain threatens to worsen landslides triggered by the earthquake, including a major slip that has blocked Vanuatu's main seaport.
