Church claimed retailers hadn't been hurt by the growing popularity of online shopping and internet sale sites because shoppers revelled in the "madness" of Christmas shopping.
"Christmas is the time where you put the kids in the car and stress yourself stupid for the day - online shopping is too sterile for Christmas."

"Saturday will be particularly busy with people doing last-minute shopping."
Santa's Enchanted Forest and popular window displays at Smith and Caughey's on Auckland's Queen St had great "pulling power" said store spokesperson Terry Cornelius.

Deb McGhie of Westfield St Lukes said Christmas shopping kicked off last weekend but she expected the madness to start this week as the school term ended.
