After six long years, a decision on ChristChurch Cathedral appears to be imminent.

The iconic building has been cordoned off since being severely damaged in the 2011 February earthquake.

The expertise is there if the push to rebuild Christchurch's Anglican cathedral, gets some divine intervention.

Architect and design director Natasha Cockerall told Mike Hosking rebuilding would be a massively challenging job, but the people power is there.

"In terms of labour expertise we do have some very good specialists in this country. We've got a lot imported from the UK and Ireland, especially in Christchurch, so I think we have got the people to do it."

Ms Cockerall said the only problem would be money - but she said a lot in the cathedral can be re-used.

"Particularly the stone works they'll be looking to reuse as much as possible. It's all in the realms of possibility, it's just going to cost a lot of money."

Former Christchurch Mayor Sir Bob Parker told Rachel Smalley he favours rebuilding the cathedral with a modern twist similar to Berlin's Kaiser Wilhelm Memorial Church which was damaged in World War Two.

"They kept a big element of that cathedral. They made it safe so that people could walk around it and go in to it, to remind people of what had happened."
