The same advice goes to anyone who attended a private event at Gurudwara Mata Sahib Kaur Ji Temple in Te Rapa last weekend.
The event was visited by an infected person last Saturday between 1pm and 4pm.
It is unknown whether these two locations were visited by people infected with the highly contagious Omicron variant.
An update on today's Covid-19 cases is expected after 1pm and the ministry is set to release many more locations of interest throughout the day.
Yesterday, a number of locations visited by cases with the Omicron variant were released.
They included a flight from Auckland to Nelson, the CityFitness Fraser Cove in Tauranga and a private event at Hamilton Gardens Pavilion.

Meanwhile, a dozen concertgoers who attended the Soundsplash music festival in Waikato last weekend have now tested positive for Covid, an infected teenager claims.
Experts now fear the popular music festival, which saw 8506 people gather on the outskirts of Hamilton from Friday to Sunday, has the makings of a super-spreader event and even accelerated the spread of Omicron across New Zealand.
Earlier this week, the Ministry of Health confirmed one of five infected Aucklanders who attended the festival had tested positive for the highly contagious Omicron variant, and the three-day event at Mystery Creek was now an exposure site.
