There are now 198 community cases in Auckland, the epicentre of the outbreak. A further 12 are in Wellington.
The country recorded 41 cases yesterday.
"Of these 62 new cases, 36 are female and 26 are male. 40 of these are Pacific peoples, three are Māori, seven are Asian, five are European, and as yet, the ethnicity is unknown of seven," New Zealand's Minister of Health said in a statement.
"All of the cases have or are being transferred safely to a managed isolation facility, under strict infection prevention and control procedures, including the use of full PPE."
COVID-19 Response Minister Chris Hipkins and Director-General of Health Dr Ashley Bloomfield will provide an update at 1pm (local time).
Mr Hipkins wished Australia success with fighting the Delta outbreak on Twitter.
"I certainly hope Australia can get back to eliminating COVID-19 in their community so that we can go back to having a good strong open relationship as we have had with them previously," he wrote.
New Zealand's Director-General of Health Dr Ashley Bloomfield said yesterday the Delta strain of COVID-19 is like dealing with a "whole new virus".
In response to the rising case numbers, New Zealand Prime Minister Jacinda Ardern announced Monday the country will remain in a level four lockdown until at least 11.59pm on Friday.
The lockdown extension will add an extra four days to the original timeframe.
