The Northland District Health Board's Covid-19 response has cost more than $2 million.
Harry Burkhardt (Ngati Kuri), the board chairman, said that was what it took to keep Northlanders safe during April.
Northland has had 28 cases with no deaths. "We threw resources at protecting our communities," Burkhardt said.
The board spent $2.01m fighting the virus during April.
"You can look at it as a $2.01m investment in keeping 180,000 people safe from Covid-19 and yes, there's an implication on our balance sheet," Burkhardt said.
"We have mitigated community transmissions which were always a big risk," he said of New Zealand's combined national pandemic response.
