The 2.7m statue was sculpted by Auckland artist Malcolm Evans for the bronze statue unveiled outside Eden Park in July, 2011.
It was added to the New Zealand Sports Hall of Fame collection at the Dunedin Railway Station earlier this month.
"The big polystyrene and fibreglass Gallaher sculpture is the original piece I produced and from which the large bronze, now in place at the main entrance to Eden Park, was made," Evans said from Auckland yesterday.
All Black great Fred Allen unveiled the bronze statue at Eden Park on July 15 last year.
"When Malcolm finished the original he took it to a foundry to be cast in bronze," the chief executive of the New Zealand Sports Hall of Fame, Ron Palenski, said.
"In terms of size and impact it is one of the best exhibits we have in the Sports Hall of Fame.
"I'm delighted that the sculptor thought of us and thought this was an appropriate home for it.
"The 1905 All Blacks and Gallaher were original inductees. They have such a high status in New Zealand, so it is appropriate that it is here.
"We can say to the people at Eden Park that they just have a copy. We have the original."
Gallaher played for New Zealand in the country's first rugby test, against Australia, in 1903 and captained the All Blacks on their pathfinding tour of the United Kingdom, France and North America in 1905-06.
Gallaher was the first to lead a New Zealand team called the All Blacks.
Gallaher played 36 games, including six tests, for the All Blacks between 1903 and 1906.
He was later an Auckland and New Zealand selector.
He enlisted in the army in World War I and was killed in action in the battle at Passchendaele on October 4, 1917, at the age of 43.
The bronze statue at Eden Park was commissioned by Gallaher's Ponsonby Rugby club and given to the Auckland Rugby Union to mark Gallaher's contribution to New Zealand rugby.
It was crafted over a six month period leading up to the World Cup last year.
