"The RBNZ will want to provide continuity given the current election-impasse and with a new RBNZ Governor at the helm," said Tuffley.
Bank of New Zealand head of research Stephen Toplis said the chances of there being any change in tack are very low: "With a new acting governor in place, policy uncertainties in abundance, and nothing much changed since the monetary policy statement, it would be a real surprise if there was any hint of a change."
Any change - should it come - is likely to be more hawkish with the New Zealand dollar lower than expected, the world outlook improving, commodity prices robust, fiscal policy easing and inflation forecasts likely to be revised higher, he said.
However, "any suggestion of a hawkish tilt would still likely see fixed interest markets sell off and the NZD rally. The RBNZ will do its best to avoid this even if its sentiment is shifting," said Toplis.
Kiwibank chief economist Zoe Wallis also said she is expecting little change in tone, with the bulk of the policy statement unchanged. "We maintain our view that the RBNZ will leave the OCR unchanged until the end of 2018, before gradually hiking interest rates," she said.
ANZ Bank New Zealand's chief economist Cameron Bagrie also said the central bank is unlikely to rock the boat and is expecting it to "reiterate a cautious, watchful and neutral stance." He noted the economy is not performing poorly, but "neither is it strong enough to change the inflation profile." While the housing market has cooled "we suspect the RBNZ is still more worried about it taking off again than about the risk it slows further," he said.
All this is likely to reinforce to the bank that "numerous uncertainties remain," leaving it happy with its view, Bagrie said.
Not everyone thinks the central bank will stay on the sidelines for an extended period, however. Annette Beacher, head of economic analysis in Asia for TD Securities, isn't expecting any move Thursday but is tipping the RBNZ to begin lifting rates in February - ahead of the median. "I don't think Spencer is going to sit back and be caretaker. He is going to join the global narrative of policy normalisation," she said.
