The number of people claiming benefits has jumped by more than 23,000 people, compared to this time last year.
According to just-released monthly data, 310,000 people are now on benefits.
That's an 8 per cent increase compared to March last year.
Last week alone, numbers rose 10,700, mostly for the JobSeeker benefit.
The number of people seeking the JobSeeker payment is up more than 15 per cent on the same time last year – or 20,000 more people.
However, most of the increase does not take into account the impact of Covid-19.
"You can expect an increase that's for sure," Minister for Social Development Carmel Sepuloni told MPs on the Epidemic Response Committee this morning.
About 152,000 people now claim the unemployment benefit - an increase of almost 6000 people in the past month alone.
Within a week, 22,000 applied for the benefit, however many of these were duplicates and not all were approved.
The data comes as the economy grapples with the economic impact of Covid-19.
The benefit numbers are expected to rise this month, and after the Government's wage subsidy expires.
Sepuloni said from now on the ministry would be releasing benefit numbers weekly.
She did not have figures on how high unemployment will climb, although Treasury did, she said.
That unemployment data will be unveiled next week.
National leader and response committee chairman Simon Bridges said Sepuloni should at least be providing estimates.
But she said revealing this information prematurely would not be in the public interest.
Sepuloni said a lot of people who were working in the hospitality sector have moved to working in horticulture – for example in the kiwifruit sector.
Both Sepuloni and Hipkins fronted to the committee this morning.
Several officials will outline the Government's Covid-19 response in terms of education and social development.
There will also be a lot of interest in the $88 million distance learning package Hipkins unveiled yesterday.
The Ministry of Social Development (MSD) has yet to update its figures, but more up-to-date data is coming out around midday, the Herald understands.
New Zealand's unemployment rate is expected to increase dramatically because of the economic impacts of Covid-19.
Treasury Secretary Caralee McLiesh said this week that she expected the unemployment rate to rise to between 5 per cent and "well into double digits".
That's a significant increase on the current 4.3 per cent unemployment rate.
Finance Minister Grant Robertson has said the Government was expecting more people to go on benefits.
As a result the Ministry of Social Development (MSD) would be beefed up, he said.
He said this week the impact of Covid-19 would be a "quantum" worse than that of the 2008/09 global financial crisis (GFC), when unemployment rose to 6.7 per cent.
Sepuloni is expected to be questioned about the increase, and whether or not the ministry can handle it.
