There are a record 163 new cases of Covid-19 today: 159 in Auckland and four in Waikato. 

The previous record, 162, was set on Monday. 

A second person isolating at home with Covid has died. Paramedics attended a Mt Eden address. 

"The man is understood to have been recently treated in hospital," director of public health Caroline McElnay said. 

McElnay and Deputy Prime Minister Grant Robertson provided today's Covid-19 update 
after the small Taranaki town of Stratford confirmed Delta had been detected in its wastewater. 

Both of the self-isolation deaths were under investigation "in order to identify any improvements that may be needed," McElnay said. 

"I want to add my condolences to the friends and family of the person who has passed away," Robertson said. 

He said the person "was admitted to hospital on the 1st of November and they discharged themselves on the 3rd." 

There are 69 people in hospital, six of them in ICU or high-dependency units. 

All but one of the 69 hospitalised cases are in Auckland. The other is in Waikato. 

Regarding locations of interest, in Auckland the approach had shifted from listing every location to only high-list events. 

Low risk places like supermarkets will no longer be listed, they said. 

High-risk sites such as gyms, indoor recreation and movie theatres will be listed. 

"We will continue to publish casual exposure events in other parts of NZ, because there are much fewer of those," McElnay said. 

Three of the four new cases in Waikato are linked to existing cases. One is still under investigation. 

The patient at Waikato Hospital is in a stable condition. 

Regarding Stratford wastewater testing, McElnay said it had not yet been linked to any known active cases. 

"Testing is really important to tell us if there are any undetected cases in that community." 

People who received their first jab on Super Saturday three weeks ago were reminded to get their second shot this weekend. 

Eden Park will be open for vaccinations at the weekend. 

The Government had paid $5.3 billion in economic support so far, Robertson said. 

The seventh round of the wage subsidy will open next Friday. As of yesterday, $1.357b was paid in wage subsidies. 

"I am proud of the economic support that we have provided. 

"We will continue to support businesses." 

Robertson said the Government was committed to allowing Aucklanders to leave the city over Christmas. 

"We're doing everything we can to make sure that happens," Robertson said. 

"It's a big job. We're working through the options." 

Taranaki iwi Ngāti Ruanui revealed this morning that Delta was detected in Stratford's wastewater yesterday. 

"We were notified last night of a strong positive Covid-19 wastewater test result, indicating the detection of the virus in the wastewater system of Stratford," iwi kaiwhakahaere Rachel Rae said. 

The sample was taken on November 1, Rae said. 

Taranaki has one of the lowest vaccination rates in the country, with 68 per cent of the eligible population fully vaccinated, and 85 per cent with a first dose. In Stratford, the stats are slightly lower with 63.66 per cent of residents double dosed, and 80.86 single jabbed. 

Rae said that the Ministry of Health was "urgently scrambling" to see if a recent MIQ returnee travelled to Stratford after being released. 

The ministry reported yesterday the death of a 40-year-old man isolating at his Manukau apartment was not vaccine-related. 

The man's death was referred to the Coroner, who will determine whether it was coronavirus-related, officials confirmed. 

The Northern Region Health Coordination Centre and the ministry will review the public health and clinical oversight of the person, with independent input. 

Across Auckland's three district health boards, 92 per cent of all eligible people have had their first dose and 82 per cent have had their second. 

Northland has seen vaccinations rise to 80 per cent of first doses and 66 per cent for second. 

Waikato was at 87 per cent for first doses and 74 per cent fully dosed.
