Properties renovated on prime time reality television show The Block are likely to be caught by the Government's new capital gains rules.
The TV3 show, which is heading into its fourth season this year, sees four teams, mostly couples, compete to do up houses which are then auctioned off live on television.
Couples get to keep whatever the property sells for over the reserve price and the team with the biggest margin gets an extra $80,000.
Rival renovation show, TVNZ's Our First Home, follows a similar format but three contestant families individually purchase their do-up West Auckland properties and keep the total sales proceeds after live auctions.
The Herald revealed in February that under the current taxation regime, Our First Home contestants would be liable for tax of up to 33 per cent on any capital gain as they were purchasing with the intention to renovate and sell for a profit.
