A study has detailed the extent prices in New Caledonia are higher than in mainland France.
It found that on average the cost for food, transport and housing are 34 percent higher.
The figures, which were compiled by the statistics office for the year 2010 and published in the local newspaper, show that food prices are 65 percent higher.
Housing, water and energy cost 39 percent more as do clothes and furniture.
There was little difference for transport costs, with New Caledonia being less than one percent more expensive.
The study noted that all French overseas territories are more expensive, with French Polynesia being 26 percent more costly.
It didn't look at the cause of the differences.
