Click Monday's organisers are expecting a strong uptake by shoppers when the online marketing event kicks off this evening.
The local version of the Northern Hemisphere's "Cyber Monday" will begin at 7pm tonight and run for 24 hours.
More than 80 retailers - including Briscoes, Rebel Sport, Hallenstein Brothers, Glassons, Whitcoulls, Icebreaker and Smith & Caughey - are taking part.
All of the brands will list their deals on a central website, clickmonday.co.nz, and shoppers will be able to click through to retailers' websites to make purchases.
Cate Bryant, an e-commerce consultant who organised Click Monday, said a number of additional retailers had signed up for the event since Friday, including children's clothing retailer Pumpkin Patch and Dick Smith.
