Woolworths says supermarket sales increased nearly 4% to $NZ1.3 billion in New Zealand in the second quarter.
The Australian retailer, which owns the Woolworths, Countdown and Foodtown chains here, says sales at stores open at least a year rose 3%.
Overall, Australia's biggest supermarket operator saw sales rise 8% to $A13.3 billion.
While the group maintained its forecasts of sales growth for 2009, it warned there is a lot of uncertainty about the economy.
It cited the difficulty of predicting inflation, volatile fuel prices, interest rates, rising unemployment and consumer confidence.
