He noted, however, the Aussie jobs data tends to be erratic and the kiwi's inflation data is unlikely to move the dial for the RBNZ ahead of its February 12 monetary policy review.
A Bloomberg poll showed the median expect 0.4 per cent quarter-on-quarter increase in CPI in the fourth quarter, with annual inflation ticking up to 1.8 percent.
The RBNZ forecast December quarter inflation would lift 0.2 per cent and annual inflation would be 1.6 per cent.Houlahan said the pound may also be fairly volatile as the UK heads toward the official January 31 Brexit date.
He said the Bank of England looks to be leaning toward an interest rate cut and noted the UK has traditionally used the weaker currency to help support the economy. They may opt to "let the pound be a bit shorter and allow that to help the economy through the transition." It is due to make a decision January 30.
