On Monday, Auckland Mayor Wayne Brown revealed his plan for a 7.9% rates increase to pay for City Rail Link running costs of an estimated $235 million annually. 

This is the largest rate rise since Auckland Council was formed in 2010.

Questions have begun arising of the legitimacy of Wayne Browns calculation of City Rail Link's projected running costs.

Auckland Ratepayers Alliance spokesperson Jordan Williams told Heather du Plessis-Allan, "you're entitled to your own opinion or your political strategy, but you're not entitled to your own facts. And the facts are Auckland Transport have have called this out as being absolute nonsense."
