There are 188 new community cases of Covid-19, the Ministry of Health announced. 

Fourteen people are in hospital, including one in ICU. 

Breaking down today's new community cases, there are 16 in Northland, including seven which were first announced yesterday. 

Of the nine remaining cases, six are in Kerikeri and three are in Whangārei and all are under investigation to determine whether they are linked to existing cases. 

There are 117 cases in Auckland as health and welfare providers support 2,495 people in the region to isolate at home, including 997 cases. 

In Waikato, there are 15 new cases with 12 linked to previous cases and three under investigation. 

Of the new Waikato cases, there are nine in Hamilton, one in Ohaupo, one in Te Kūiti, one in Huntly, one in Waimiha, and locations for the remaining three are under investigation. 

There is one new case to report in Tairāwhiti today, who is a household contact of an existing case and was already isolating when they tested positive. 

Cases peaked at a record daily high of 243 on Saturday but dipped slightly to 208 yesterday, while epidemiologist Michael Baker said New Zealand's current average doubling time of 4–5 days is lower than what was previously seen overseas. 

Baker said this reflects how spread was being slowed down due to by the current traffic light settings and contact tracing efforts. There were 128 new cases reported in Auckland yesterday. 

Two popular bars and church services emerged as the latest locations of interest: 

Anyone at the One80 Restaurant in Oriental Bay's Copthorne Hotel in Wellington between 9pm and 10.30pm on Saturday is considered a close contact of a case and should self-isolate and get tested immediately. 

Three new high-risk locations of interest were also announced by health officials in Hamilton. 

• Islamic Centre Masjid Frankton: Sun, Jan 30, 8pm–9.30pm
• Islamic Centre Masjid Frankton: Mon, Jan 31, 8.15pm–10.15pm
• Private event at the Guru Nanak Sikh Temple Puketaha: Mon, Jan 31: 8.45am–5.15pm

Anyone who was at any of the three locations during the affected times is considered a close contact and is advised to self-isolate and get a test immediately. 

Meanwhile mobile testing was offered at the Tahuna Beach Holiday Park in Nelson yesterday after a case was identified there. The source of infection is under investigation. 

Further cases were identified in Northland, Waikato, Lakes, Bay of Plenty, Hawke's Bay, Wellington, Nelson Marlborough and South Canterbury. 

Around half of all eligible people have now received their booster jab - with a record number administered on Friday. 

There were 48,947 booster doses administered yesterday, taking the total to date to 1.5 million. 

The Ministry of Health is urging all other eligible people to get their booster immediately, saying it's "one of the best things you can do" with the Omicron variant in New Zealand. 

People are also being reminded to get tested if they have Covid-19 symptoms. 

There were 100,000 fewer tests administered in the week following Omicron community transmission than the week following Delta transmission, Ministry of Health data shows. 

Experts said testing rates should be higher because testing is still a key measure in slowing the spread of Omicron. 

Meanwhile schools are preparing for sickness and new teaching arrangements as Omicron spreads throughout the region. 

Western Bay of Plenty Principals Association president Suzanne Billington said primary schools in the region were preparing to teach students off-site and on-site at the same time. 

Twelve people are receiving hospital care across Auckland, Waikato, Rotorua and Christchurch. One person is in an intensive care unit in Rotorua. 

Nineteen new cases were identified yesterday at the border among recent returnees.
