A SHARP jump in the price of leading stock New Zealand Telecom boosted the Wellington blue chip index to its highest close since May 1990.
Interest rates, which have now fallen half a percentage point since Thursday's budget to 20-year lows, were also a spur for equities. The NZSE-40 Capital Index rose 16.46 to 1,715.52.
Volume was NZ$38.2 million, high for a Monday, considering the US holiday weekend.
''There is more capacity for the market overall to react in a positive manner to these falls in the wholesale interest rate market because they are very material,'' said Ord Minnett equities director John Rattray.
SYDNEY THE Australian share market closed slightly lower, with gold the only feature in otherwise subdued trade.
Gold stocks were firmer, but failed to inspire the broader market and most key stocks fell.
The All Ordinaries Index closed three points down at 1,765.9 after opening 4.6 points down.
