New Zealand shares fell as the attraction of yield stocks lost their lustre now most have shed rights to dividends. Retirement village operators such as Metlifecare and Ryman Healthcare extended their decline.

The S&P/NZX 50 index dropped for a sixth session, down 79.34 points, or 0.8 per cent, at 9,707.96. Within the index, 31 stocks fell, 14 gained, and five were unchanged. Turnover was $150.4 million.

Stocks across Asia were broadly weaker, following Wall Street's lead, as ongoing trade tensions between the US and China and a downgraded global growth outlook from the International Monetary Fund kept investors uneasy.

Property and utilities stocks, which typically pay reliable dividends, were the most traded stocks. A number of companies gave up recent gains after shedding rights to their recently announced dividend payments.


Several of those yield plays have been trading near records as investors who would usually seek stable returns in corporate bonds have sought higher returns in the low interest rate environment. The NZX50's average dividend yield of 4.83 per cent is the third highest across Asia-Pacific benchmark indices tracked by Refinitiv.

"A lot of investors who require yield were forced up the risk curve and took on equity risk rather than corporate bonds, where rates are now getting issued in the low-to-mid-threes," said Matt Goodson, managing director at Salt Funds Management.

Spark New Zealand was the most traded stock on a volume of 4 million shares and was down 2.1 per cent at $3.575. Meridian Energy dropped 2.2 per cent to $3.97 on a volume of 2.9 million shares and Kiwi Property Group was down 0.7 per cent at $1.465 on a volume of 1.5 million shares.

Among other companies trading on volumes of more than a million shares, Fletcher Building fell 1.4 per cent to $4.96, Contact Energy fell 1.2 per cent to $6.67, Precinct Properties New Zealand decreased 0.3 per cent to $1.555, A2 Milk Co declined 0.7 per cent to $14.62, Argosy Property was unchanged at $1.27 and Sky Network Television fell 1.6 per cent to a new low of $1.24.

Retirement stocks remained under pressure after Summerset Group cited slowing property markets in Auckland and Christchurch for denting its first-quarter unit sales. Metlifecare led the market lower, down 2.4 percent at $4.47 on a volume of 672,000 shares, more than three times its 90-day average of 196,000.

Ryman fell 1.7 per cent to $11.560 on a volume of 1.2 million shares, compared to its 439,000 average. Summerset was down 0.4 per cent at $5.53 on a volume of 888,000, more than twice its 288,000 average.

Goodson said the property market slowdown will probably show greater diversity across the different companies, which have enjoyed a tailwind of rising house prices and an ageing population for several years.

"The housing slowdown is really only in Auckland and Christchurch at this stage. If it does spread more widely, the balance sheets of these businesses could come under a bit of examination," he said.


Arvida Group rose 0.8 per cent to $1.31.

Trustpower fell 2.4 per cent to $6.98 after saying annual earnings were in the middle of its guidance, and warning 2020 earnings may fall on a decline in generation and fewer mass market customer numbers.

Chorus fell 1.6 per cent to $5.955 after reporting an increase in broadband connections in the March quarter, as new fibre customers outpaced a decline in copper line customers.

Air New Zealand posted the biggest gain on the day, up 2.4 per cent at $2.81, on a volume of 967,000 shares. Port of Tauranga rose 1.8 per cent to $5.60, and Scales Corp was up 0.6 per cent at $5.03.

Outside the benchmark index, Hallenstein Glasson fell 5.5 per cent, or 27 cents, to $4.68, after shedding rights to a 20-cent interim dividend.
