Christchurch's transitional cathedral will be one step closer to completion when the estimated 15- tonne Trinity Window is installed on Thursday.
The Anglican Diocese is spending about $4 million on the construction of the temporary transitional cathedral, otherwise known as the Cardboard Cathedral.
The diocese's spokesperson, Jayson Rhodes, said the Trinity Window's frame would be lifted up into place on Thursday and the pieces of glass fitted in the coming week.
He said the window would be the centrepiece alongside the Rose Window which was damaged during the earthquake.
Mr Rhodes said the cathedral was expected to be open to the public in early June.
