The ANZ's latest survey has found quarterly economic activity has risen in most regions.
The bank's regional trends report found activity rose 0.7 percent in the three months to March quarter, led by Northland, Bay of Plenty and Waikato.
While activity rose in eleven regions, it declined in Taranaki, Southland and Gisborne.
The bank's economists say business and consumer confidence remains high, which is underpinning higher production, hiring and investing by firms, and consumer spending.
On an annual basis, economic activity eased slightly from 4.2 percent to 4.1 percent.
