For the Bay, with strong kiwifruit and forestry sectors, the exposure to dairy risk was only about 1.2 times the national average, whereas in key dairy sectors the risk rose to more than four times.
"The Bay has industries that are driving growth. We know kiwifruit is an incredible success story."
In addition, New Zealand prices for forest products had remained remarkably strong. "Forestry has held up. China mostly takes the low-end exports for boxing with higher quality exports going to the US and Australia and we are seeing higher value forestry exports stay up."
Mr Norman said one of the key factors underpinning economic activity was increased population growth generally, which was partly being driven by the fact that New Zealanders were not leaving in such large numbers.
"The world is becoming less about building stuff and more about consumption of services. The attractiveness of Australia as a labour market is a lot lower."
The Bay now had the highest population growth since the 1970s. While Auckland got the bulk of new migrants from China, India and the Philippines, which make up the top three categories of new arrivals, the Bay was seeing population growth from within New Zealand, both from Auckland and other regions.
And more people meant more demand for services, schools and houses, he said.
