The New Zealand dollar is tracking toward its highest level against the euro in more than a year, driven by growing market conviction that the Reserve Bank of New Zealand (RBNZ) will maintain a tighter monetary stance than the European Central Bank.

This divergence is reshaping cross-currency flows, with investors rotating into higher-yielding assets in the Asia-Pacific region.

The move follows a recent rally in the kiwi against the US dollar, where the currency climbed 0.4% on Friday to reach $0.5778, marking a three-week high.
