New Zealand shares fell for a fifth session as retirement village operators Summerset Group and Metlifecare suffered amid fears a slowing property market will dent their fortunes.

The S&P/NZX 50 Index declined 19.78 points, or 0.2 per cent, to 9,787.30. Within the index, 16 stocks fell, 24 gained, and 10 were unchanged. Turnover was $143.9 million.

Summerset led the market lower, down 3.8 per cent at $5.55 on a volume of 1.2 million shares. Its 90-day average is 281,000. Metlifecare fell 3.2 per cent to $4.58 and Ryman Healthcare declined 2.5 per cent to $11.70.

Last week, Summerset warned that first-quarter unit sales were down in part because of slowing property markets in Auckland and Christchurch. Rapid gains in house prices in recent years have been a tailwind for the sector, which is busy building new villages in anticipation of the needs for an ageing population.


"Uncertainty around the housing market is coming home to roost with a lot of the premium starting to disappear for some of those stocks, particularly Metlifecare and Summerset," said Grant Davies, an investment adviser at Hamilton Hindin Greene.

"If you look at the two stocks in the sector not as exposed to property, Arvida is holding its ground where it is and Oceania is also holding its ground reasonably solidly."

Arvida was unchanged at $1.30, while Oceania Healthcare, which is outside the benchmark index, slipped 1 per cent to $1.

The NZX50 has been coming off the boil during the past week after hitting a record and toying with the 10,000 level. The large number of listed companies paying reliable dividends has been an attraction for investors in search of yield in a low interest rate environment. However, since most of the companies that reported in February have shed rights to their dividends, that appeal has dulled.

Mercury NZ fell 0.8 per cent to $3.88 on a volume of a million shares. Chair Joan Withers yesterday announced her plans to retire from the board at this year's September annual meeting.

Contact Energy declined 0.9 per cent to $6.75, on a volume of 1.4 million, while Genesis Energy was down 0.2 per cent at $3.085.

Of those companies reporting next month, Mainfreight decreased 0.6 per cent to $35.90. Fisher & Paykel Healthcare declined 1.3 per cent to $15.05.

Spark New Zealand was the most traded stock on a volume of 3.2 million shares, less than its 6 million 90-day average. It decreased 1.2 per cent to $3.65. Air New Zealand increased 0.2 per cent to $2.745 on a volume of 2.2 million shares and Kiwi Property Group fell 0.7 per cent to $1.475 on a volume of 2.3 million.

Tourism Holdings posted the biggest gain, up 4.6 per cent at $5.19 on a smaller volume than usual of 88,000 shares. The rental RV operator's joint venture with Thor Industries - TH2 - announced the merger of its CamperMate and RoadTrippers businesses with Australia's GoSeeAustralia and Outdoria to create a single trans-Tasman entity.

Pushpay Holdings rose 2.3 per cent to $3.56 on a smaller than usual volume of 222,000 shares. Gentrack Group increased 1.3 per cent to $5.52 on a slightly larger volume than average of 104,000.

Outside the benchmark index, Paysauce jumped 27 per cent, or 0.3 of a cent, to 1.4 cents, after more than doubling March quarter recurring revenue.
