Transparency Solomon Islands says a recent spate of arrests and convictions for corruption is welcome.
Last week, the MP Dixon Mua was arrested and charged for misuing a shipping grant.
The police commissioner Matthew Varley says 10 other MPs were also under investigation.
Then on Monday, the former permanent secretary of the police ministry Edmund Sikua was convicted on three corruption charges.
He will be sentenced on Wednesday.
Transparency's Ruth Liloqula says this is welcome news, but she told Jamie Tahana that with elections looming, more needs to be done.
