"As set out in our Trans-Tasman bubble protocols, travel between New Zealand and Western Australia has been paused, pending further advice from the state government," a statement on the New Zealand government website said.
Earlier on Friday the Perth and Peel regions were sent into a three-day lockdown after Western Australia recorded its first community transmission of the virus in 12 months.
A man in his 50s, who recently left hotel quarantine, flew into Melbourne from Perth on Wednesday and tested positive for the coronavirus earlier on Friday.
One of the man's close contacts in Perth also tested positive for the virus, raising concerns that it may have spread further into the community.

Despite testing negative for the virus before leaving hotel quarantine -- a requirement for all international arrivals to Australia -- authorities believe the man likely contracted Covid-19 from another hotel guest.
"He spent up to five days in Perth, and we now need to assume he was infectious," Western Australia premier Mark McGowan told a press conference.
Other Australian states and territories, whose residents are still able to fly to New Zealand under the bubble arrangement, moved to restrict arrivals from Western Australia following the outbreak.
The few instances of community transmission in recent months have been linked to hotel quarantine in major cities, and all the outbreaks have been successfully contained with similar brief lockdowns.
It is the first major snag since New Zealand and Australia opened their quarantine-free travel bubble on April 18, almost 400 days after both closed their international borders due to the pandemic.
The bubble, which followed months of negotiations between the largely coronavirus-free neighbours, was hailed as a major milestone in restarting a global travel industry that has been crippled by the Covid-19 pandemic.
Before Covid-19 brought New Zealand's tourism industry to its knees, it was the country's biggest export industry, with Australians accounting for about 40 percent of the international visitors.
The rate of new coronavirus cases has abated significantly in both countries without straining the capacity of their health systems. New Zealand has enforced a wide-ranging lockdown and Australia is also tightly restricting many activities.
Tourists will be able to stay overnight from June 1 in regional areas in the southern state of Victoria, where "tourism is such an important part, especially for bushfire-affected communities", state Premier Daniel Andrews said on Sunday.
Australia will within weeks allow residents of New Zealand to enter the country without having to quarantine, Deputy Prime Minister Michael McCormack said on Friday, as Canberra seeks to revive its ailing economy as COVID-19 cases begin to slow.
