Scott said the New Zealand dollar's recent strength, rising from below 65 US cents last month to more than 68 cents, has hurt exporters such as Fisher & Paykel Healthcare, whose shares fell 0.5 per cent to $12.90.

However, a number of the yield stocks have been relatively unscathed.
Pharmaceuticals distributor and veterinary company Ebos Group shares rose 0.9 per cent to $21.99, Genesis Energy gained 0.8 per cent to $2.50 and Meridian Energy was up 0.2 per cent at $3.25.

The trade war threat weighed heavily on tech stocks in the US overnight, with the Nasdaq down 3 per cent. That weighed on local growth stocks such as Pushpay, which extended its decline, falling 4.8 per cent to $3 on higher than average volume. Tourism Holdings, another growth stock, dropped 4.6 per cent to $4.60 on lighter volume than normal.
