A piece of art made in support of earthquake-hit Christchurch by one of New Zealand's most notable contemporary artists is being auctioned to save the NG building.
The late Ralph Hotere gifted Hang in There Mate to the Madras St building's owners in 2013 with specific instructions that it is used to help save the building from demolition.
Its future is currently uncertain as it sits on land intended for the planned $473 million multi-use arena.
The Crown is currently in the final stages of compulsory acquisition for land to begin the project.
However, its owners, Sharon Ng and Roland Logan, have obtained interim court orders to maintain ownership of the building and the matter is expected to be argued in the High Court on Thursday.
To support efforts to save the building an art auction is planned for later this month which will include Hotere's piece.
Fifty artists from around the country have contributed works with 40 per cent of the proceeds going towards the building and 60 per cent going back to the artists.
Logan said the more than 50 works have valuations, but they couldn't put a price on the main piece.
"Ralph has given it to raise funds and give awareness to saving the building so I think it should be used for that. I think it's up to the public to put a value on it."
Logan said they've worked hard to save the building after the quakes, and now with the stadium.
"It's going to be a lottery ticket, like all actions even if you do have a good case and we'll either win it or lose it and if we lose it we lose the building. They just take it off of you."
The auction will be held at the NG building on May 20 starting at 6pm. Tickets can be purchased here.
Registration for bidding will open from 10am on the day. Complimentary drinks and nibbles will be provided.
The building is the last of the Victorian and Edwardian style warehouses seen in Christchurch in the early 1900's.
It escaped the worst of the earthquakes and was one of the first buildings to reopen in the city.
The spokesperson said when the stadium was first proposed in 2012, the building was incorporated into the original designs.
"Early this year, to the shock of the owners and tenants, new designs were suddenly released.
"The new plan stated abruptly that it required the building to be demolished, and the Crown began the process of compulsory acquisition of the NG building."
The spokesperson said they are not opposed to the construction of the stadium, they only want to save the building.
