Customers were expected to keep streaming in until closing time at 10pm tonight and the Christmas rush would likely continue when trading hours were extended to midnight on Monday, Riley said.
"It's only going to get busier during the week. Christmas has always been busy, but I think this one is going to be slightly busier. We've just seen an edge up on where were last year."
Westfield spokeswoman Debra McGhie said all six New Zealand centres had been busy today, with St Lukes and Albany drawing particularly big crowds.
"They've been full on."
It was difficult to predict whether Westfield malls would get even busier this week, McGhie said, because some people would be heading out of town before Christmas, while others would leave all their shopping to Christmas Eve.
"Traditionally that last weekend before Christmas is busy, but last year there were a couple days during the week that spiked too. What the weather's doing comes into it as well."
Both McGhie and Riley said specific figures on foot traffic and turnover today were unavailable.
