Transparency International Papua New Guinea is praising the Minister for National Planning, Charles Abel, for showing how he spent funds allocated to him under the District Services Improvement Programme.
Mr Abel had the spending detailed in the local newspapers.
TI says with this information voter can make informed decisions about the effectiveness of their representatives.
It says it would like all MPs and government officials to provide details of spending in the same accurate and timely manner.
And TI endorses Mr Abel's call for the Office of Rural Development to enforce compliance as legally required.
The watchdog agency says a lack of accountability and transparency in the expenditure of public funds in the past has greatly contributed to the decline in trust in political and public institutions.
