The cases are being heard across the country including in the Auckland, Waitākere, Christchurch and Hawera District Courts.
One of those cases resulted in a guilty plea in the Auckland District Court in February when the individual admitted three charges of receiving wage subsidy funds they were not entitled to, totalling $18,745.60, which they have since repaid.
Sentencing is expected to happen this year.
That case was understood to be the first criminal prosecution relating to improper access to the "high-trust" subsidy scheme.
MSD's fraud investigators have completed 14,836 pre-payment and post-payment checks on wage subsidy applications, resolved 5553 allegations of wage subsidy misuse, completed 533 wage subsidy-related investigations, and to date recouped $797.9 million in wage subsidy repayments.
A spokesman for MSD said more prosecutions were to come as investigations into individuals and businesses are completed.
MSD has also referred 10 cases involving larger sums of money and complex investigation to the Serious Fraud Office.
Data released in May showed the wage subsidy schemes had supported 47 per cent of jobs in the country.
In 2020, 69 per cent of employed men and 54 per cent of women were supported by a wage subsidy.
This fell to 54 per cent and 41 per cent respectively in 2021.
