Canterbury's struggling artists feel the purchase of pricey international sculptures is a slap in the face.

The two works by British artist Antony Gormley have divided the city, with many local artists wondering why the contract wasn't put out to tender.

While the council's put up more than $500,000, CERA is refusing to disclose its contribution.

Local sculptor Ruth Killoran said it's an insult to local artists trying to make a living.

"Before the quakes I was doing really well, and things were taking off, and then of course we took a hit."

"There are artists who are really struggling who could have benefited from that money."

She added that it was wrong, and too much to spend.

South Island sculptor Trevor Askin says everyone should've been involved in designing something for their own city.

"Well I think there's a name factor here, without a doubt. There should have been a tender put out and submissions put in by different artists on what they envisioned and conceptualised."

However, despite the hefty price tag, Christchurch Art Gallery's director is right behind two international sculptures heading for the city.

Jenny Harper said despite her own budget being cut this year, it's a win for the city.

"I think it's amazing to have two sculptures by Antony Gormley. We don't always have to be local. There are other sculptors who we should have, I agree, but this is an amazing opportunity."
