The Ministry of Health has revealed a new location of interest visited by the Grand Millennium border worker.
The positive case was a 24-year-old security guard at the Grand Millennium MIQ facility in Auckland.
Director-General of Health Dr Ashley Bloomfield revealed the worker had not yet been vaccinated.
The 24-year-old returned a positive COVID-19 result after being tested on Tuesday. A second test result on Thursday also returned a positive result.
Fifteen close contacts have been identified. All have been contacted and are self-isolating.
Thirteen have returned negative test results.
Location of interest
The Ministry of Health has so far identified one location of interest visited by the border worker.
It is the Bikanervala bakery at 2 White Swan Road, Mt Roskill on April 7 between 1:30 and 2:30pm.
Further locations of interest are expected and will be announced as soon as they are confirmed.
Anyone who visited this location at the time is considered a casual contact and should monitor for any symptoms. If you begin to feel unwell or develop any COVID-19 symptoms, contact Healthline on 0800 358 5453, get tested and stay at home.
A list of testing centres in Auckland is available here.
Case investigations continue
The investigation into how the worker at the Grand Millennium MIQ facility became infected with COVID-19 continues.
The 24-year-old lives alone and travels to work with a colleague - a close contact. They have been contacted and are self-isolating.
The initial investigation found the person returned high CT values which can mean they are either early on in their infection, nearing the end, or the case is historical.
The Ministry of Health urges New Zealanders to be vigilant and continue to stay at home if unwell and get tested if you develop any COVID-19 symptoms.
