New Zealand shares gained in shortened Christmas Eve trading, shaking off the negative lead set by Wall Street's decline on Friday night, with defensive stocks such as property investment firms and power companies among the gainers.

The S&P/NZX 50 index increased 28.32 points, or 0.3 percent, to 8,714.51. Within the index, 28 stocks gained, 15 fell, and seven were unchanged. Turnover was very light at $49.1 million.

New Zealand's market held up well in the abbreviated trading session after Wall Street was bashed by the heightened political uncertainty in the US, where a stalemate among policymakers has led to a federal government shutdown. Meanwhile, White House divisions are re-emerging with President Donald Trump forcing an early exit for Secretary of Defense Jim Mattis, who resigned over the president's decision to withdraw from Syria.

Grant Williamson, a director at Hamilton Hindin Greene, said the global uncertainty has meant the traditional rise in markets through Christmas and New Year isn't likely to happen this year. Global equities markets have gained into the Christmas period about 80 percent of the time since the 1940s in a phenomenon so common that it has been dubbed the 'Santa rally'.


"It seems as if the market was firm today - obviously Wall Street had a big fall on Friday night and we're not really following suit," he said.

The NZX50 is among the few benchmarks still up in the year-to-date, with a 3.8 percent gain.

Williamson said the correction in global markets has been reasonably orderly.

Stride Property led the market higher, up 3.2 percent at $1.92 on very light volumes. Sister company Investore Property, which Stride manages, gained 2 percent to $1.54, also on light volumes. Kiwi Property Group increased 1.9 percent to $1.37 and Argosy Propety was up 1.7 percent at $1.20.
