She said it could be sold as a whole or broken into its components, which included an inflatable cover, a stage, lighting, stairways and sound systems, but not the projection system that displayed the striking images of New Zealand's landscape to the world.
The successful bidder would also get the five shipping containers needed to transport the ball around.
Ms Adams said the ball had played a unique role in promoting the country: "To have that New Zealand presence in such prominent places, it seemed to get away with being a billboard in very unlikely places where they have strict management of any kind of advertising.
"I think it's served its purpose really well and it's time to move on. It's still in good nick, and you know, one door closes and another opens."
Ms Adams said it was well-suited to a 200-person, two-storeyed function room or exhibition space, but it would always be oval shaped. Even if the inflatable rugby-ball exterior was removed, the interior was also egg-shaped.
The ball's construction was believed to have cost around $2 million.
