This chart above shows the annual increase in the median house price for every year since 2000. Note the 2021 figure is for June 20 to June 21, the rest are calendar years.
There was sold growth from 2003 to 2006. From 2007 to 2011 only one year had growth of over $20,000.
2016 and 2017 saw pretty large growth – what Labour called a crisis. But they pale in comparison to 2019, 2020 and 2021 to date. 2019 saw larger growth than any previous year. 2020 saw an average increase more than double the worst year under National. And the last 12 months has seen larger growth than a combined eight of the nine years under National.
