Mystery sabotage of developer Williams Corporation's reputation

A mystery person is trying to sabotage the reputation of Christchurch's biggest high-density home builder, the Williams Corporation.
At its most recent three developments, flyers have been delivered to neighbours, purporting to be from the Williams Corporation, but making outrageous claims.
The managing director has had enough and put up a $4000 reward for information about the person responsible.
RNZ reporter Katie Todd has the story.
