Angee Shand, a spokeswoman for the Invercargill Licensing Trust (ILT), which commissioned the mural, said it had been in consultation with the scaffolding company.
Scaffolding would be removed on Thursday, and the reveal would take place at 11am on Friday.
Mrs Shand said the ILT was "really excited.''
A combination of high wind and rain had prevented the unveiling taking place yesterday.
The ILT believes the mural on the Kelvin Hotel, on the corner of Esk and Kelvin Sts, will be one of the tallest street murals in New Zealand.
Street artist Danny (Deow) Owen was commissioned to create the mural in December.
