On Monday, it was reported an Australian man had received a positive Covid-19 test after returning to his Melbourne home, following a stint in South Australias hotel quarantine system.
The man had arrived back in Australia from India, via the Maldives and Singapore, on May 4.
He developed symptoms on May 8 and got tested on May 10, returning a positive result on Tuesday morning.
Shortly afterwards, Victorian health authorities published seven locations of interest linked to the case.
Four of those locations have been categorised as tier 1, which means anyone who visited about the same time should get tested immediately and quarantine for 14 days from exposure.
Director-General of Health Dr Ashley Bloomfield said on Tuesday that the public health risk to New Zealand was low.
The ministry has recommended quarantine-free travel can continue between Victoria and New Zealand.
The total number of active cases in New Zealand is 18. The total number of confirmed cases is now 2289.
