A right-wing fringe group in the UK has questioned whether same-sex marriage in New Zealand led to the “destruction of Wellington” in an earthquake.

The London Swinton Circle sent out a newsletter connecting the legislation introducing gay marriage last year and "the recent destruction of Wellington by earthquake."

The destructive Christchurch earthquake happened more than a year before Louisa Wall's bill was pulled from the ballot.

A gay group that's highlighted the comment has asked if the group’s “lack of compassion and human decency is second only to their lack of geography and geology”.
