Nielsen figures show the average weekly audience during peak hours has dropped about 30 per cent. Interestingly, viewer numbers for off-peak viewing have increased by about 25 per cent.

Bravo wouldn't comment on the network's performance, instead pointing to their online engagement, which is more than double that of FOUR during the same month last year.
It's understood several other local reality franchises are under consideration, including Million Dollar Listing. However, any further investment will be dependent on the success of Housewives.
Insiders are confident Kiwis will be charmed by the cast, with several picking Anne Batley Burton - aka the "Champagne Lady" - as the breakout star of the show.
In addition to importing French wine and Champagne, she is a well-known animal advocate, who founded the NZ Cat Foundation to care for stray cats.
