It will take the form of a steel sculpture, created by Mark Hill, and have pride of place on Fraser's West Rock Stack in the Macraes Heritage and Art Park.
The eagle, which has been extinct for at least 500 years, was the largest in the world, with a wingspan of 3m.
Its remains have been found throughout the South Island, including in the Macraes, east Otago, area.
The sculpture stands 8m tall and has a 12m wingspan.
"It's going to be big; you won't miss it," Oceana tourism development co-ordinator Graham Wilson said.
Mr Hill, son of jeweller Michael Hill, had an interest in eagles and was keen to become involved in the project.
"The mounting on its tail allows the huge talons to extend in an attacking swoop, giving the impression of life and movement," Mr Hill said.
The sculpture will be flown by helicopter to the site, where it will be installed on December 18 and 19.
It will join four other pieces of art in the park, which will be officially opened in January 2009.
