Dean of Christchurch

Following the September earthquake Beck was invited to become the patron of CanCERN, a network of community groups advocating a stronger voice for local communities.

Following the February 2011 Christchurch earthquake, Beck made himself available to the media, and was widely quoted,^{[1][9][10][11]} with one in particular often cited:^[12][13][14]

The earthquake was not an act of God. The earthquake was the planet doing its thing the way the planet does. For me as a Christian, the act of God is in the love and compassion that people are sharing among each other.

Gareth Farr composed a memorial piece for the Christchurch earthquake, Nor'West Arch, first performed on 25 September 2011. The title makes reference to a particular Christchurch weather pattern, but is also that part of the ChristChurch Cathedral that received most damage in the earthquake. Beck was part of the performance, reading an introduction including the quotation above.^[15][16] The concert was one of the highlights of the 2011 Christchurch Arts Festival.^[17]
