The New Zealand dollar is near the top of its six-month range ahead of Thursday's monetary policy statement, and will probably hold around its current level this week.
Six of eight economists and strategists in a BusinessDesk survey expect the currency will trade in a flat range this week, with the greatest risk coming from Reserve Bank Governor Alan Bollard's statement on Thursday.

The kiwi climbed to 72.96 US cents from 72.52 cents on Friday in New York, paring a month high 73.24 cents, after strong Chinese data on Saturday stoked investors' appetite for riskier, or higher-yielding, assets, and encouraged traders to bump up the New Zealand dollar.
The upbeat global sentiment has eased any concerns investors might have about this week's monetary policy statement.

"The Reserve Bank should be dovish which would add extra weight on the kiwi, but the bullish global theme will win," said Imre Speizer, market strategist at Westpac Banking Corp.

"There's been a huge jump up on calls on the VIX - people are picking volatility in equities," he said.
Kelleher predicts the kiwi will be capped by recent ranges this week.

"The big issue focus for G-7 nations is Basel IIII regulations,"
Jones said. "It will have a material impact on European banks, and they will need to raise equity to meet the new rules."
