A suggestion that Fisher and Paykel Healthcare product could be used in home diagnosis led to a recovery in its share price and in the local stock market generally.
The S&P/NZX 50 Index gained 70.12 points or 0.61 per cent to 11,609.22, and 48 million shares worth $154.41 million changed hands. There were 57 gainers and 78 decliners over the whole market.
Fisher and Paykel recovered the previous day's losses and more, rising $1.23 or 3.94 per cent to $32.42 on trade worth $32.42m.
Rickey Ward, JBWere head of investment strategy group, said a broker's note in the United States indicated that a study was under way to find ways of funding home medical diagnosis.
"The expectation of home diagnosis in the United States and Europe has been brought forward because of Covid," he said. "People can be tested and treated in the comfort and security of their homes rather than be put into situations of mass gatherings and higher risk.
"This benefits companies like Fisher and Paykel which produces sleep apnea and high-flow technology such as humidifiers. Home diagnosis is an enormous market," Ward said.
Fisher and Paykel's competitor in Australia, ResMed, also had a strong rise on the S&P/ASX 200 Index, climbing 71c or 3.06 per cent to A$23.86 ($25.82).
Ward said the lower trading on the New Zealand market was a sign that stocks were well owned or it is going into a holiday period and focusing on the election policies being provided by the different parties.

"If you buy online, the products have to be couriered from A to B and Freightways has benefited. There are also more people working from home – and that's another effect of Covid."
