UPDATE: A man is his 80s is the fifth person to die from a COVID-19 related illness in New Zealand.

Director-General of Health Dr Ashley Bloomfield says he is the third person in the Rosewood Resthome cluster to pass away.

There are a total of 33 people involved in this cluster - 17 confirmed and 16 probable.

Ashley says the man was being cared for at Burwood Hospital after being transferred from Rosewood Resthome in Christchurch.

"We know that because of the underlying vulnerabilities of this group we need to be prepared for further illness and possible death."

There are now 33 COVID-19 cases involved with the Rosewood Cluster.

"Thirteen of the 33 were residents and 18 are staff."

He says there are now 15 clusters around the country.

Today, there are 15 confirmed cases and four probable casses of COVID-19 in New Zealand.

This brings the total number of cases to 1349.

Ashley says the number of people who have recovered from the virus is now at 546.

He says this is 75 more than yesterday.

"Fifteen people remain in hospital, four in ICU and one person is in critical condition."

Ashley will be hosting a Facebook Live event at 2.15pm to answer any questions the country may have about the virus.

This will be hosted on the Ministry of Health Facebook page.

Speaking at the same media conference, Prime Minister Jacinda Ardern says she hoped despite obvious restrictions, people had been able to have a meaningful Easter.

Bu the news of the fifth death was a "timely reminder that our battle with this virus is far from over".

Jacinda says the number of cases may be small but that doesn't mean we have successfully "hunted the virus down".

To those who broke the lockdown rules weekend, she says it takes just one case to spread among others.

If the country moved to level three, people should treat it as a live "waiting room".

She says the government will this week set out details of what different alert levels would look like.

Further details of the impact on the economy will be released this week, including the impact on business and this year's budget.

"I understand the importance of this information for businesses and industry to plan."
