Foreign patients in Hawke's Bay owed almost $80,000 for medical treatment as of December.
Figures released under the Official Information Act, show 53 foreign patients owed a total of $79,662 in unpaid medical bills at the end of 2014.
However, the amount owed was a sharp drop on previous years. In 2013, 88 debtors owed $408,545 and in 2012, 66 debtors owed $392,807.
The Government foots the bill for New Zealanders but foreign patients have to fill out an eligibility form when they turn up at hospital.
A Hawke's Bay District Health Board (DHB) spokeswoman said the board alerted immigration to ineligible patients' debts and referred them to a debt collection agency.
