Outdoor retailer Kathmandu's sales increased more than 30% for the quarter ended May 1, underpinned by Easter promotional sales and fine weather.
The company is predicting growth in sales and profit for the year, while remaining exposed to the "key risks" of changes in economic activity and weather patterns.
Total sales were up 31.6% for the quarter, while year-to-date sales were up 23.1%, Kathmandu's chief executive Peter Halkett said.
"Clearly, this has been a particularly good period for us, but it was in comparison to a relatively poor performance for the same period in 2010," he said in a market statement.
Kathmandu shares surged on the news, initially up more than 6%, or 15c, to trade around $2.60.
Forsyth Barr broker Suzanne Kinnaird said she expected continued good performance, although much would depend on the last quarter to July, which was Kathmandu's peak quarter.
"The strong New Zealand dollar versus the US dollar will be helping offset cost increases coming out of China and thus maintaining margins," she said.
Kathmandu sales in New Zealand (36 outlets) and Australia (58) were both up more than 20%, while sales at its six United Kingdom shops were down.
While Kathmandu was producing the strongest current performance of any listed New Zealand retailer, Ms Kinnaird cautioned profitability could be volatile.
Mr Halkett said Kathmandu "remains on track to deliver strong year-on-year sales and profit growth" given the trading performance during the third quarter built on an earlier 19.2% sales increase during the first half year's trading, the latter's earnings before interest and tax being up 28.4% on the previous corresponding period.
• Kathmandu signalled in March its capital expenditure would be up on last year's at $13.6 million, which included increasing the number of outlets from 100 to 112 by July.
