New Zealand's economy probably accelerated in the first quarter on construction activity, supporting the central bank's view that it must press on with interest rate increases to keep inflation at bay.
The economy grew 1.1 percent in the first three months of the year, from a 0.9 percent pace in the fourth quarter of 2013, economists and the central bank forecast. That would mark the fifth quarter with growth of 1 percent or above in the past six years.
Last week, the Reserve Bank said the economy's expansion had "considerable momentum" and raised its estimate for growth in the first half of the year to 4 percent from 3.5 percent.
Net immigration that's expected to peak near 40,000 this year and income growth are seen underpinning economic demand. The data on Thursday is likely to be a key figure for investors betting on whether the central bank will lift rates again at its next review in July.
"The RBNZ highlighted at the June MPS the boost much stronger than expected net migration will have on housing and household demand," said Nick Tuffley, chief economist at ASB. "Along with the emerging recovery in business investment, the RBNZ is mindful that such strong activity will see spare capacity diminish rapidly. Construction cost inflation is a key concern for the RBNZ given the surge in construction activity."
