"Given the events of 2020 and the impact of Covid, to finish the year down only 3 per cent from 2019 is phenomenal," Tuffley said.
"However, we need to remember that much of that drop is concentrated in the tourism sector, which continues to be held back by the border closure."
Given how strongly households have responded to recent low mortgage rates, ASB no longer expects the RBNZ to cut the OCR to a negative level.
"China's rebound has been particularly good for our key commodity and food exports, which have held up well," he said.
For the 12 months ending September, exports of dairy, meat, fruit and wine were all well above the previous year, which has helped offset the 43 per cent decline in the export of services, in particular international tourism."
"Given the global challenges, we remain relatively cautious about the pace of growth for 2021 and 2022," Tuffley said.
"We expect growth prospects to be muted over 2021 with the border likely to stay closed, and weak global growth limiting our export performance."
