Hon GRANT ROBERTSON: Many and varied. ANZ chief economist, Sharon Zollner, says the bank expects today's announcements to have a meaningful impact on investor housing demand and to make "a decent start on the complex question of improving house supply." Infometrics economist Brad Olsen says, "The Government has been told there was a problem … and has acted on it." I've also received several emails today, including one from a member of the public that I'll quote briefly: "Dear Ms Ardern and Mr Robertson, I am delighted to see the measures you have announced this morning to finally tilt the housing market away a bit from those investors who have been writing off interest costs against rental income and making untaxed profits for so long at the expense of struggling home buyers. The adjustment has been needed for a long time and I am thrilled that finally my youngest son, along with so many young people, may have a chance in the next few years to contemplate purchasing his own home."
