The annual register of MP's pecuniary interests was released in April, revealing the property holdings of our political representatives. While property investors have been the target of some heavy political criticism recently, 81 of our 121 MPs own more than one property.

Many MPs who have interests in more than one property own a family home and a holiday home, but others have far more significant investment portfolios.

The three MPs with the biggest property holdings are all from the National Party.

Minister of Justice Amy Adams, Minister for Primary Industries Nathan Guy and first time National list MP Parmjeet Parmar each has ownership stakes in seven properties.

Adams has stakes in a residential property, two commercial properties, a farm, a vacant section and two lots of bare land.

Along with his family home, Guy has stakes in a farm (with four dwellings), a house, two rental properties, a bare section and interests in commercial properties.

Besides his family home, Parmar also has stakes in four rental properties, a commercial and residential property and a commercial property.

National’s Jacqui Dean and Barbara Kuriger and, perhaps surprisingly, Green MP Kevin Hague have interests in six properties.

Another seven MPs have interests in five properties. They are all National Party MPs.

Further, Labour MPs Adrian Rurawhe, Rino Tirikatene, and Poto Williams, and NZ First deputy leader Ron Mark, have stakes in multiple blocks of Maori land – on top of other properties.

Nearly half of the MPs with interests in more than one property own at least one property in Auckland.

This means many will have been the beneficiaries of the SuperCity’s record-breaking house price growth over the last couple of years.

Forty MPs have interests in just one property or less, including 11 who have no property interests.
