New Zealanders' shopping spree could be slowing down

Data from payment company Worldline NZ shows consumer spending through its network - excluding hospitality - reached 100.5 million dollars on Boxing Day.

That's up 2.6 percent on the same day last year.

Spending over the three weeks before Christmas Day also rose 0.8 percent to 2.89 billion dollars.

But economist Brad Olsen says people are expected to tighten their wallets from now on.
