The fun starts in the central business district from 6pm when people can buy "Mr Whanganui Money" from stands at Majestic Square, the corner of Victoria Ave and Ridgway St, and Victoria Ave and Guyton St.
They then check out the men standing in shop windows, each one representing a different charity, and vote for their favourite bloke by giving them the Mr Whanganui Money.
At the end of the night, the bills are exchanged for real money and donated to each chosen charity and the man with the most bills is crowned Mr Whanganui 2015.
The promotion - which raised $9700 in just three hours for 30 local charities last year - is run by Mainstreet Wanganui.
It's Mr Cleveland's first tilt at the title but he is confident enough to have a side bet with last year's Mr Whanganui, Chronicle general manager Andy Jarden, with $100 going to the charity of which ever one gets most votes.
Mr Jarden, supporting Parkinson's NZ, will be offering foot massages at Victoria Ave shoe shop Footloose and rides in his cadillac.
