Analysts at ANZ point out that the RBNZ has surprised investors with a shift towards an explicit easing bias at its March meeting and the market pricing shifted aggressively, with 50bps of cuts priced in by the end of 2019.

• "Long-end yields have pre-empted a cut but we expect there will be another move lower once the first cut is delivered and markets open up to the possibility of a third. The Fed’s stance will likely cap any further upward moves in the long end, while there may be a brief repricing at the short end of the New Zealand curve following the RBNZ’s May meeting.”
