"The RBNZ cut rates, which was a bit of a surprise in choosing not to follow the lead of the Federal Reserve and RBA," said Greg Smith, head of research at Fat Prophets.
Smith said the impact of the rate cut on the economy will depend on where the central bank settles on imposing tougher capital requirements on banks.
"Even if you ease on rates, if you start tightening up on lending you won't have a meaningful impact on the economy."
Skellerup Holdings led the market higher, up 5.3 per cent at $2.38, on a volume of 158,000 shares. Its 90-day average is 203,000. The rubber goods maker's industrial unit has been expanding its international business and is a beneficiary of a weaker currency. The RBNZ's rate cut immediately knocked the kiwi dollar down more than half a US cent. It was recently at 65.87 US cents.

Pushpay Holdings posted the biggest decline on the day, down 2.9 per cent at $3.71 on a volume of 2.9 million shares - about eight times its 90-day average.
The mobile payments system provider today reported an annual profit and was cashflow positive. However, chief executive and founder Chris Heaslip announced he was stepping back from the management team, while retaining his directorship. Chair Bruce Gordon will take over the CEO role.
Smith said Pushpay's result was reasonably good, meeting expectations, but that Heaslip's exit was a surprise.
"Although Gordon has experience and is a safe pair of hands, there's a bit of trepidation when a founder steps away," he said.
Synlait Milk fell 1.5 per cent to $10.50 on a typically small volume of 29,000 shares. The milk processor said the government's new methane targets were in line with the company's own sustainability targets.
