The Block NZ is TV3's highest rating show this year and it surely must have set some sort of open home records last weekend when thousands lined up for a nosey at the contestants handiwork.
And next week the four couples - Ginny and Rhys, Rachel and Tyson, Ben and Libby, and Sarah and Richard - will be hoping the show's popularity will help fetch them a good result when their houses go under the hammer at auction.
On Wednesday, in the penultimate episode, the contestants backyard renovation is revealed and there are a few final challenges to do before they get on to marketing their houses and preparing for the open homes.
The following night the two-hour finale features the live auction of the houses. Each team will get to keep any profit they make at the auction, and those with the biggest gain also pocket a further $80,000.
Spokesperson Rachel Lorimer says TV3 is delighted with the success of the multimillion-dollar reality show.
