Rivers is due to have a bail application later this month.
“The wage subsidy scheme provided an unprecedented level of financial assistance to support New Zealand’s economic recovery from Covid-19 and we are committed to identifying and investigating any instances of misuse,” Van Ooyen said.
“Our pipeline of investigations has so far resulted in 36 people being brought before the courts for wage subsidy misuse.”
Van Ooyen said the total amount of public money involved in these cases was about $3m.
And another 12 cases were in the process of having charges filed, he said.
“Eight people have been convicted and sentenced to date, while another six are awaiting sentencing.”
Van Ooyen said the MSD was also undertaking civil recovery action in relation to 31 businesses, with civil court action having started in seven of these cases.
“We expect more court cases to follow as we continue our investigations, which involve a mix of individuals and businesses,” he added.
It’s understood cases involving allegations exceeding $1m generally get assigned to the Serious Fraud Office (SFO).
Van Ooyen said the SFO filed 95 charges against Hun Min Im, who is alleged to have fraudulently claimed more than $2.3m from various Covid-19 relief funds and GST returns.
But Im allegedly received $624,000, less than the amount Rivers is accused of fraudulently receiving.
Fraud investigators accused Im of using applications with false information to acquire the subsidies.
It was not immediately clear how Rivers was accused of gaining the wage subsidy payments and he could not immediately be reached for comment.
The MSD said it had completed more than 15,000 pre-payment and post-payment checks on wage subsidy applications, and resolved 6703 allegations of wage subsidy misuse by the end of March.
Thousands of Kiwis have already made voluntary repayments, Van Ooyen said.
“This has contributed to 24,732 voluntary and requested wage subsidy repayments being made, totalling $819.1 million.”
To receive the wage subsidy, applicants had to sign a declaration stating they operated a business in New Zealand, registered charity, incorporated society, NGO, post settlement governance entity or, in specified circumstances, a commonly-owned group.
