Fisher & Paykel Healthcare added 2.3 per cent to $10.51, benefiting from a tumble in the New Zealand dollar in the wake of the central bank's announcement.
Xero led the benchmark index higher, rising 5.3 per cent to $23 after the company said its net loss was $69.1m, narrower than the $82.5m reported in the prior period. Chief executive Rod Drury didn't specify when the company might report a maiden profit but did note the company was ebitda-positive in the second half of the year, excluding share-based payments, and the operating cash flow also moved into positive territory. "You can see where we are making progress on all those things," he said.
Z Energy added 0.8 per cent to $7.89 after it more than tripled its annual profit after acquiring Chevron New Zealand's Caltex and Challenge! brands. Profit jumped to $243m, or 61 cents per share, in the 12 months ended March 31, from $64m, or 16 cents, the year earlier, it said.
A2 Milk also helping bolster the index, adding 3.5 per cent to $3.80, as investors continue to be cheered about its prospects in China, said Williamson. "It's in a major uptrend," he said.
In the other direction, the biggest loser was Sky Network Television, which shed 1.9 per cent to $3.66. The stock has struggled to gain any traction since the Commerce Commission rejected a tie-up between the pay-TV operator and telecommunications group Vodafone New Zealand
Some profit taking in Heartland Bank weighed on the index as it ended down 1.7 per cent at $1.78. The stock rose sharply earlier in the week on news that its Australian-owned banks faced new deposit levies across the Tasman. The dual-listed Australian banks rallied somewhat after chief executives of the 'big four' banks hinted that costs from the recently announced federal tax could be passed on to customers. Australia & New Zealand Banking Group rose 1.3 per cent to $31.58 while Westpac Banking Corp added 0.8 per cent to $35.07.
Tilt Renewables, which operates wind and solar generation facilities, ended flat at $2.14 after reporting its first result since its demerger from Trustpower, which was completed on October 31, 2016. The company reported a 44 per cent slide in net profit to A$16.4m, driven lower by higher depreciation and higher income tax expenses following the demerger. Trustpower added 1.4 per cent to $4.97.
