I see that the DCNZ have now added the following on the P N Liston reference to the website, quote :

“Fellowship in Dental Surgery, Royal College of Surgeons of England, United Kingdom, 1995

This practitioner was registered under section 15(2) of the Health Practitioners Competence Assurance Act 2003, with their qualification(s) considered equivalent to, or as satisfactory as, a prescribed qualification for the particular scope of practice. This is not a comprehensive list of the practitioner’s qualifications, training and experience.”

A very convenient way to try to stymie any awkward questions.  This does not change the fact that he is still under qualified (as confirmed by the Royal College of Surgeons, London) but the DCNZ register him on the basis that he has a “vocational” qualification.

This is the email from The Royal college of Surgeons, London :

Dear Ms Rigg,

Many thanks for your emails to our Head of Membership.  Ms Cunliffe has passed your emails to me.  As Ms Cunliffe informed you, Dr Liston is no longer a Fellow of this College – his fellowship having lapsed, and therefore he cannot use the postnominals FDSRCS.  I have emailed him to remind him of this and to ask that he returns his Diploma to this College.  Under data protection regulations in the UK, we are unable to confirm further details, such as the date of the lapse of Dr Liston’s fellowship of the College.  If you have further concerns, you may wish to contact the Dental Council of New Zealand. Their website may be found athttps://www.dcnz.org.nz/  I hope that this helps to confirm the current position.

Kindest regards,


Elizabeth Anderson

This is what was stated by one of his peers, quote:

Liston trained at a time when the current specialist registration requirements did not apply, the specialist registration requirements currently are different to those that applied years ago.  Obviously for those who are trained overseas the DCNZ are asked to look at individual qualifications to determine equivalence or to register them on a vocational basis, like Liston.”

  • Email from DCNZ with regard to the above waffle, flannel, or what ever you want to call it, quote:

    The New Zealand Medical Council is a separate regulatory authority to the Dental Council. A medical practitioner must be registered with the Medical Council to practice in New Zealand and oral health practitioners must be registered by the Dental Council to practice here.  Each practitioner’s registration (for both Medical Council and Dental Council)  covers a “scope of practice” in which they are registered to practice.

    Medical practitioners registered by the Medical Council can apply for registration in the “Oral & Maxillofacial Surgery” scope of practice.

    Oral health practitioners registered by the Dental Council can apply for registration in the “Oral and Maxillofacial Surgery Specialist” scope of practice. 

    The scope of practice is a detailed and technical document that sets out the parameters of practice i.e. what the practitioner can and can’t do legally within their practice as either a medical practitioner or an oral health practitioner.  Some oral health practitioners are also qualified as medical practitioners and vice versa. These practitioners can choose to be registered by both Councils depending on the nature of their practice.

  • Email from Valentina Vassiliadis of the DCNZ, with regard to the complaint against the misrepresentation of post-nominals used by OMS Peter Napier Liston, quote

    "We refer to earlier email communications with you regarding Dr Peter Liston, and wish to update you on the outcome of your complaint about the advertising of Dr Liston’s qualification.  We have received confirmation from the Royal College of Surgeons that under the rules of the College, Dr Liston may continue to state he took the Royal College of Surgeons of England examination but, as he has allowed his membership subscription to lapse, he is no longer entitled to use the post-nominals, as doing so would imply his continued membership of the College.  Having taken up the matter with Dr Liston, we are satisfied that he has now taken the appropriate action to remedy his advertising.  In particular, the post-nominal letters FDSRCS have been removed from advertising associated with his practice.  In addition, the post-nominals for his qualification are no longer displayed on the Dental Council public register.  Changes were made to the Dental Council public register as part of its recent implementation of a new IT system—including,

    • Describing qualifications in full, rather than using acronyms or abbreviation.
    • Clarifying that the qualifications displayed on the register are those that granted a practitioner registration for a particular scope of practice. This clarification appears as a text box when the cursor hovers over ‘Qualification(s)’.

    The Dental Council’s intent with these changes is to make it clearer to the public of New Zealand what qualifications granted a practitioner registration in their scope/s of practise.

    Thank you for bringing your concerns to our attention.

    Kind regards

     End of quote.

    I will add to this missive with a question regarding the last sentence, quote “The Dental Council’s intent with these changes is to make it clearer to the public of New Zealand what qualifications granted a practitioner registration in their scope/s of practise.”  It is not what qualifications are granted to a practitioner it is what registration is granted by the DCNZ.  The DCNZ need to check that qualifications are what they say they are - verification is or should be required before that person is allowed to practice.  In the case of this surgeon he has been in practice for almost 20 years.
