His work visa ended in July 2007.
He renewed his annual practising certificate twice while living in New Zealand, the last of which expired in March 2008.
In June 2008, Mr Laverty was employed at TLab in Gisborne and worked there for 10 months before starting his job at Pathlab in Tauranga.
Ms J Hughson, who appeared at the tribunal hearing representing the Professional Conduct Committee, said it could not have been a matter of pure coincidence that Mr Laverty stopped renewing his practising certificate in the very practising year when his last valid work visa had expired.
Ms Hughson referred to Mr Laverty's dishonesty when he represented to his Tauranga and Gisborne employers that he held a current APC and permanent residence "when he must have known that he did not hold one".
"Indeed in his CV he falsely stated that he was a permanent New Zealand resident," she said.
"Then in July 2013 when his employer asked him to supply his passport number he provided Pathlab with an invalid number and Pathlab then had to make its own enquiries of Immigration New Zealand to establish that Mr Laverty was not legally able to be in New Zealand."
Ms Hughson said Mr Laverty's offending "involved a significant level of deception ... the offending involved multiple breaches of trust".
The tribunal said was ample evidence Mr Laverty knew he did not hold a practising certificate.
He had failed to tell the Medical Sciences Council of changes to his contact details, which the tribunal stated may have enabled him to avoid detection for so long.
"In others [cases] the practitioner has, through simple inadvertence, practised without a practising certificate for a short period of time, and the tribunal has obviously had some sympathy for his or her position. In short, we have not found a case which is similar to this.
"In our view, for any professional person knowingly to practise without a practising certificate is, in and of itself, serious ... very serious indeed."
