New Zealanders continued to wind back their spending in the lead-up to Christmas after a short-lived splurge during the Rugby World Cup.
The value of total electronic transactions fell 0.2 percent to a seasonally adjusted $6.6 billion in December, according to Statistics New Zealand.
That follows a 0.3 per cent decline in November and a 1.7 per cent decrease in October 2011, as households continue to keep a lid on their spending.
Spending in core retail industries, which strips out vehicle related spending, fell 0.1 per cent.
"The December result suggests the boost to spending from the Rugby World Cup was short-lived, which was to be expected," ASB economist Christina Leung said in a note.
