The Anglican Bishop of Christchurch, Victoria Matthews, says they are extremely privileged to have the Archbishop there.

Bob Parker is showing the Archbishop of Canterbury around the city's red zone today.
On a bus tour, he told Dr Rowan Williams about new technological sites being established in the city.
He says it's the beginning of the rebuild of an electronics hub.
Bob Parker says a lot of people don't realise there's a huge number of electronics firms around the city because of the University.
The Archbishop of Canterbury will conclude his visit down under tomorrow in Auckland.
It's his last international duty before standing down after ten years as worldwide head of the Anglican Church.
