Samoa's umbrella body for non government organisations, SUNGO, is calling on the government to subsidise the price of fuel.
This comes after the Electric Power Corporation announced another 20-percent increase in fuel surcharges from the middle of August after a hike in June.
The fuel surcharge has gone up by 46 percent in two months.
SUNGO's chief executive Roina Vavatau says it's the poor who will suffer the most from increased living costs.
"I don't think there's any other way out unless government provides a subsidy for petrol imports. And that's the only way how I can see how the country coping. For us who are working at this level, we can barely afford to provide now and to meet running costs. But I think there should be some sort of national strategy as to how people can learn to cope."
