"Overall, the impact of the UK's exit from the EU on the New Zealand economy is uncertain as this stage, but is not considered likely to be significant, at least in the short-term," Treasury said.
Over a longer horizon, the Treasury warned the impact of the Brexit on New Zealand will probably be negative, but the extent of that will depend on how long financial market volatility persists, and how the UK will settle on its new trading partner relationships.
Last week, Finance Minister Bill English said New Zealand was better placed than most countries to deal with any fall-out caused by the Brexit vote, with the government's finances stable, the economy growing and room for interest rates to move lower if necessary.
The Treasury today said the country was "in a relatively strong position to withstand any shock", while acknowledging that "any shock could still have a material impact on the New Zealand economy."
