"New Zealand has strengths that I think make it resilient to the global economy at the present time," Hess said, citing falling government debt that is below other similarly rated countries, improving prospects for service exports such as tourism and education, and booming immigration.
"These are all these positive aspects that are offsetting any negatives that are coming from the farm sector," he said.
Should the economy weaken, government finances are strong and it could use its balance sheet to offset any potential shocks, while the Reserve Bank also had the ability to lower interest rates if needed, he said.
"We are not seeing big risks," Hess said.
A correction in the housing market, particularly in Auckland, remained a risk although Moody's didn't rate that risk very high, given prices were underpinned by demand from strong immigration, he said.
