Meet the contestants on this year's The Block NZ!

The Block NZ 12/06/2017

Later this month hit series The Block NZ returns to Three, with four new teams renovating four homes on Auckland's North Shore.

They're the largest houses in series history, each with three bedrooms, three bathrooms and a double garage.

Each also shares a stunning roof terrace which boasts spectacular views of the city, harbour and Rangitoto Island.

This year's contestants are:

The teams have 12 weeks to complete their three-storey family homes.

This year the footprint of the houses is almost identical, so the teams will need to really push the boundaries and showcase their design skills to earn the highest price on auction day.

MediaWorks is pleased to confirm the return of all our programme partners from last season, along with some great new partners joining for the first time.

Broadcast sponsor AMP is proud to be back along with Freedom, Pita Pit and new partner NZ Post.

The Block NZ 2017 launches on June 25 at 7pm.
