WELLINGTON, New Zealand — New Zealand reported no new virus cases in the community for a second day, raising hopes a lockdown in Auckland will be lifted Wednesday.

The three-day lockdown of New Zealand’s largest city was the nation’s first in six months.

Lawmakers say their final decision on whether to lift the lockdown will depend on any new information or cases that crop up over the next day.

The lockdown was prompted by the diagnoses of three family members, but how they got it remains a mystery.

The mother in the family works at a catering company that does laundry for airlines, and a possible link to infected passengers is being investigated. So far, other people at her workplace have tested negative, officials said.

Health officials have ramped up testing, administering more than 15,000 tests on Monday and processing the results of nearly 6,000.
