In October 2009, rules associated with tree trimming were revoked and new or amended definitions of trimming were included in district plans across Auckland.
Mr Smith said on Wednesday this had resulted in a huge drop in the number of consents issued by councils since 2009.
He said that in Auckland in 2008-09 before the rules changed a total of 2640 consents were issued. For the year ended June 2011, the number of consents dropped to 1180.
