These would be the first positive community cases in this latest outbreak outside of Auckland and Coromandel.
The Ministry of Health has declined to comment at this stage.
A ministry spokesperson says all confirmed cases of Covid-19 will be announced "as soon as practicable".
The government is due to announce any changes to the lockdown at 3pm.
In Auckland, there are 22 active cases of Covid-19 in the community.
The outbreak has been linked to a person who travelled to New Zealand from NSW on 7 August and transferred to hospital on 16 August.
Locations of interest can be found on the Ministry of Health website as they become available.
