Prices have been slashed by up to 70 per cent at some of New Zealand's biggest stores today for what's expected to be the biggest shopping day of the year.
The five Westfield shopping centres across Auckland and Christchurch will see countless pairs of feet march through looking for bargains today, said New Zealand regional manager Linda Trainer.
"We're expecting literally hundreds of thousands of people to come through our doors."
Trainer promised unmissable bargains, with Westfield retailers embracing Boxing Day as a huge draw for shoppers.
"It's a crazy busy wonderful day where everyone can come in and get that bargain."
Sensible shoes were a good idea, as was coming early to try and get a jump on the throngs of thrifty customers searching the malls for deals, she said.
"Try to pre-plan your visit. If you go on to our website you will find store location maps, you'll see what deals are available in the centres and parking information."
It was too early to tell whether this year would be a record-setting day of sales, but feedback from retailers indicated the pre-Christmas lead-up had been a healthy one this year, Trainer said.
Westfield shopping centres will be open from 9am to 7pm today.
Last year Kiwis spent more than ever before on Boxing Day, setting a record $152.7 million of spending through Paymark, according to the company's figures.
It was a 1.9 per cent increase in spending on 2015.
Pre-Christmas spending has risen again this year, with expectations the holiday period could be another record year for retailers.
On Thursday Kiwis spent $282.4 million in a single day, with 178 transactions per second during the peak which occurred just after noon - a new record.
Major retailers are embracing the sale day.
The Warehouse's communications manager Becki Butler said there would be bargains store-wide, including 10 per cent off iPhones, 50 to 60 per cent off Daewoo appliances and Veon 32" TVs selling for $189.
Buy one get one half price deals would also be available for men's and women's clothing, toys and a range of outdoor gear.
"Our Boxing Day bargains will be available online from 9pm Christmas Eve and most stores open at 7am on Boxing Day," Butler said.
Jason Bell, merchandise manager at Noel Leeming, said Boxing Day was the biggest trading day of the year.
Stores would be offering 20 per cent off everything Panasonic, 25 per cent off Fisher and Paykel products and 50 per cent off all Sunbeam appliances.

On top of the brand-specific deals, one-off "huge savings" could be made on several gadgets including $300 off the Samsung Galaxy S8 which would be retailing for $849 and $1000 off LG's 60" TV which was reduced from $2499 to $1499.
