The New Zealand dollar tumbled more than half a US cent and recently traded at 79.90 US cents, the first time it has been below 80 cents since this time last year, after Reserve Bank governor Graeme Wheeler invoked two of the conditions for the bank to intervene in currency markets, saying its strength was "unjustified and unsustainable" given the decline in commodity prices. A weaker currency is good news for exporters, as it makes their goods more competitively priced overseas and boosts earnings when they're translated back into the kiwi dollar.
F&P Healthcare, which exports more than 90 percent of its breathing apparatus, climbed 1.6 percent to $5.14.
"The weakening currency is good for the export sector," Lister said. "There is also a general economic boost that people assume that the country will get if we see sustained currency weakness."
Pacific Edge climbed 2.3 percent to 91 cents. The medical biotech company has been awarded a Japanese patent for its colorectal cancer screening technology, as the company looks to expand its range of diagnostic tests internationally.
"When you get news flow, particularly when you're in that biotech space, you've had something that adds to your credibility from offshore markets, its going to see the share price react," Lister said.
Hallenstein Glasson jumped 9.1 percent to $3.10. The clothing chain posted a 24 percent drop in annual profit to $14.3 million but said all chains in the group are trading ahead of year earlier levels in the first seven weeks of the new financial year, with a "solid improvement" in its gross profit margin. The stock dropped out of the benchmark index earlier this year.
"That result was in line with what people were expecting anyway and they had some quite upbeat comments on how the first several weeks have gone, so that's positive," Lister said.
Fellow retailers gained on news of the positive start for Hallenstein's year. Kathmandu Holdings, the outdoor goods retailer, advanced 2.2 percent to $3.27. Warehouse Group, New Zealand's largest listed retailer, rose 0.3 percent to $3.10.

NZAX-listed Chatham Rock Phosphate climbed 15 percent to 11.5 cents after hearings began on its application to mine the Chatham Rise seabed for phosphate. The would-be undersea miner told the Environmental Protection Agency committee the phosphate is a "strategic resource of national significance" and that its project would have a limited impact on the area.
