A three-month long investigation has revealed that many of the offers available this Black Friday are not the bargain they may seem to be. 

Consumer NZ conducted an investigation into Briscoes, Noel Leeming, Farmers and Harvey Norman, and found that customers could have picked up the same items at a similar or lower price over the three-month investigation. 

Consumer NZ's Head of Research Gemma Rasmussen told Heather duPlessis-Allan that, 'there's so much hype around Black Friday, but the deals are a little dubious.'

She said that it's important consumers do their research before hitting the shops.
