A study commissioned by the World Bank suggests the quality governance in Melanesian countries has worsened in the last six years.
The research released today in Washington DC uses a percentage scale to measure six governance and anti-corruption standards in countries in 2004, compared with 1998.
These are: voice and accountability, political stability, government effectiveness, regulatory quality, rule of law and control of corruption.
The reported sharp decline in these standards in Solomon Islands stands out, but it follows a similar pattern to PNG, Fiji and Vanuatu.
The report is a statistical compilation of surveys and polls reported by institutes, think-tanks, non-governmental and international organisations.
The World Bank says the data isn't meant to indicate precise country rankings but general trends.
