The prevailing perception in Auckland's property market is that an influx of capital from China is a factor driving up prices.
NZ First leader Winston Peters challenged Prime Minister John Key to debate the issue this week. All three major Opposition parties are proposing bans or restrictions on foreign buying of homes and it could be the issue that decides who wins the September 20 election.
The Government is under pressure to at least investigate the anecdotes from auction rooms. Key and Finance Minister Bill English acknowledged this week that no one had hard data to prove or disprove the influx of capital. Key did not think buying from China was an issue, citing a survey of agents by BNZ chief economist Tony Alexander, but said the analysis was "crude".
So, the information vacuum remains and Peters and Labour leader David Cunliffe are gathering the anecdotes and rhetoric to make it a central election issue. The Government has side-stepped calls for an inquiry but has not ruled one out. This leaves a stalemate that may only be broken by a change of government or a backdown by National to secure Peters' votes.
