A man who used fake documents to pose as a doctor in South Auckland was caught after a colleague recognised him as a former fake student at the University of Auckland.
Yuvaraj Krishnan was employed at Auckland's Middlemore Hospital until questions were raised about his medical qualifications before he was sacked on 10 August.
Krishnan appeared at the Manukau District Court on Wednesday where he pleaded guilty to a charge of using a forged document to get an advantage.
Court documents revealed that Krishnan used an annual practising certificate despite knowing the certificate and accompanying email was forged.
Krishnan was believed to have worked with up to 80 patients during his time at the hospital.
In 2021, he applied for a job at the Middlemore Hospital where he sent a false certificate and fake email from the Medical Council which appeared to verify his qualifications.
The University of Auckland has confirmed he was trespassed in 2012.
Judge Jane Forrest remanded Krishnan on bail and set a sentencing date for December.
