A Canterbury DHB spokeswoman earlier confirmed to the Herald Mehta also worked for Canterbury Medical Imaging - now Canterbury Community Radiology.
Given the discovery of the sex charge, Taylor's medical council registration was cancelled in New Zealand in 2015 and up until recently he was living and working in Australia.
His medical registration was cancelled in Australia this year and now he lives in New Zealand.
After discovering his arrest, the department initiated a bid to revoke Taylor's citizenship.
The office of Minister of Internal Affairs Peter Dunne sent Taylor's counsel a letter in June 2014 stating they were seeking the revocation as Taylor failed to inform them of his history which affected the 'good character' assessment of a resident which he said was gained by "fraud, false representation, or wilful concealment of relevant information rather than by mistake".
But in March 2015, department officials changed their prosecution tack and said they were launching their bid by saying the application was granted "by mistake".
The application was granted by the minister but an appeal was launched by Taylor's counsel and was heard in the High Court earlier this year.
In her decision released this week, Justice Karen Clark found that although she agreed that Taylor's citizenship should be revoked, she was unimpressed with the department's last minute change in tack stating it was "not just a flaw in the process but a fundamental denial of Dr Taylor's entitlement to a fair opportunity to respond".
"In the context of a proposed deprivation [revocation] of citizenship the obligation to act fairly required Dr Taylor to be given a fresh opportunity to respond on each occasion the department or the minister altered its stance on the grounds for deprivation [revocation] ... the fair hearing which the department was purporting to provide to Dr Taylor was not fair and in the respects discussed his entitlement to natural justice has been breached. For these reasons the application for judicial review succeeds."
Taylor's counsel wrote the change in stance was "completely unacceptable" and the judge agreed.
"I accept [counsel's] submission that it is 'completely unacceptable', including from an evidential point of view, for a change in ministerial position to be advanced during the course of the hearing," the judge wrote.
"To my mind the notification of yet a different ground for deprivation of citizenship and the manner of the notification compounded the pre-existing breaches of natural justice."
Jeff Montgomery, general manager of citizenship at the Department of Internal Affairs, said given the judge's decision, it would now file a new application to revoke Taylor's citizenship for the minister to consider. If it's approved, and Taylor doesn't appeal, his citizenship will be revoked and his New Zealand passport cancelled.
If he remains in the country he will then be under the control of Immigration.
