The NZX 50 Index climbed to a record as a new US partner for Xero saw investors return to the sold-off stock, while high-yield power companies MightyRiverPower, Contact Energy, Meridian Energy and Genesis Energy paced gains.
The benchmark index rose 84.385 points, or 1.6 percent, to 5232.676 points. Within the index, 38 stocks rose, five fell and seven were unchanged. Turnover was $279 million. The NZX 50 climbed 1.3 percent this month, and about 10 percent in the year.
Xero, the cloud-based accounting software company chasing growth, secured a partnership with H&R Block in the US and slowed cash burn for the first three months of this year luring back investors.
The company was caught in a global tech sell-off, sliding 20 percent over the past month, as investors questioned the valuations of high-growth companies. The shares rose 5.5 percent to $31.65.
"Probably slightly better than we were expecting in terms of cash burn, down $2.5 million from the previous quarter, but I think it's more to do with the strategic partner H&R Block," said David Price, a Forsyth Barr broker. "It's a matter of seeing whether they can convert these alliances into dollars."
