They also note that core inflation appears to be rising, with capacity constraints intensifying particularly in the construction sector and tentative signs of a lift in wage growth. Inflation expectations have stabilised and the Reserve Bank's next survey of expectations for two years out will probably show a small lift, they say.
Tactically, the Reserve Bank will probably prefer to hold rates unchanged in June, as it awaits key inflation and growth data, and giving itself more time for an 'easing bias' to weigh on the currency, ANZ said.
"Baiting the market by holding but with an easing bias is not without (currency) risk. But cutting but signalling no more to come can be worse," ANZ said.
The economists put the odds of a cut in August at about 60 per cent and say global risks mean they expect the rate to fall as low as 1.75 per cent next year.
"The global situation remains vulnerable and the actions of other central banks are keeping the New Zealand dollar stronger than 'desirable'. In a world where currencies are diverging from fundamentals, interest rates must converge, and this is a force we suspect will drag the RBNZ back to the easing table at some stage," they said.
While the government has signalled a more expansionary fiscal stance in the near term, which would support activity, a greater focus on debt repayment in the medium term still argues for low rates for longer, ANZ said.
