BNZ chief economist Tony Alexander said demand for New Zealand's food exports was expected to continue growing in China, despite the slowdown. "Most of the items going into China are food and demand for that is structurally rising with the growth in the middle class."
However, Alexander said the impact of the slowdown on Australia, which is being hit by falling demand for its mineral resources in the Chinese market, would affect this country.
Australian GDP growth slowed to 0.6 per cent during the first quarter of this year, taking the annual growth rate to 2.5 per cent.
Several NZX-listed retailers, including Pumpkin Patch and Michael Hill, have already flagged tough trading conditions across the Tasman.
Alexander said the slowdown in the Australian economy meant there was a risk that the kiwi dollar could rise further against its Aussie counterpart, which would put pressure on local exporters, many of whom rely on Australia as their main market. The New Zealand dollar has risen more than 8 per cent against the Australian currency since March and was trading at A85.86c yesterday.
Glen Mackie, senior policy analyst at the NZ Forest Owners Association, said Kiwi log exporters had found themselves a niche in China, which would help shield them from a slowing Chinese economy.
"Because we've got some of the cheaper logs on the market, we don't tend to get affected quite as quickly, especially when there's an economic downturn because people tend to move to cheaper products," he said.
Sir George Fistonich, founder of Auckland's Villa Maria Estate, said their wine exports to China continued to be strong. They had been supplying China for about 14 years, mostly high-end restaurants. "We're still on a growth path but I imagine if you were a new company in the supermarkets or cheaper end of the market you could be having problems," he said.
Morningstar analyst Nachi Moghe warned this month that a sharp Chinese downturn could hurt Port of Tauranga, which relies on forestry and log exports for about 40 per cent of its trade.
