New Zealand stocks rose as a front bench Labour Party MP quit, stoking speculation the incumbent National-led government will return for a third term. Contact Energy, Vector and MightyRiverPower gained. Xero led the advance.
The NZX 50 Index rose 37.983 points, or 0.7 percent, to 5142.922. Within the index, 30 stocks rose, 11 fell and nine were unchanged. Turnover was $104 million.
Labour MP Shane Jones, who ran for the party's leadership last year, has quit politics to take up a Pacific economic ambassador post created for him by the National-led government, a move that may weaken Labour's prospects in this year's election. The opposition parties want to further regulate New Zealand's energy market, which has spooked investors from the sector.
Contact climbed 2 percent to $5.69. Government-controlled MightyRiverPower, rose 0.9 percent to $2.26, while Auckland lines company Vector advanced 0.8 percent to $2.49. TrustPower lifted 1.5 percent to $6.65. Meridian Energy fell 0.4 percent to $1.185.
Outside the benchmark index, Genesis Energy, the last asset in the government's partial-privatisation scheme to be publically listed, fell 1.1 percent to $1.81 on its third day of trading, after climbing 18 percent in its first two days of trading.
