Another Queensland mayor will be investigated by the state's Crime and Corruption Commission.

The CCC has revealed it is taking a second look into Moreton Bay Mayor Allan Sutherland's purchase of a two-hectare, $700,000 piece of land at Burpengary in 2010.

At the time, the area was earmarked for future development.

Cr Sutherland has been investigated over the purchase before, but it is believed new information may have come to light.

The CCC said in a statement it is "investigating several allegations of corrupt conduct".
