The tour also has exclusive insight into two new pieces of street art.
This includes the Scott Base and penguins mural in Cathedral Square, one of the city's largest murals.
Head of the Christchurch Antarctic Office David Kennedy said the audio tour was a jewel in the city's exploration crown.
It is enabling people to reconnect with the city's historic and contemporary links to the ice, he said.
"Ōtautahi Christchurch has always been a place of exploration and stories, with perhaps the richest Antarctic history on the planet.
"The Antarctic Gateway City Trail enables people to experience this history in depth, at the places it happened, and at their own pace."
Christchurch continues to be a hub of Antarctic activity with four international programmes using the city as a year-round base for operations.
They take advantage of both Christchurch Airport and Lyttelton Port for transport.
Hundreds of Canterbury businesses support and supply the Antarctic sector.
The Christchurch Antarctic Office recently launched the Christchurch Antarctic Network, a platform for these businesses to tell their stories of product and service delivery to the ice.
Figures from 2017 show the Antarctic sector as a whole contributes more than $250 million to the Canterbury economy and more than $500m to the national economy.
