After opening the MCNZ web site you will see
a "Find a Registered Doctor" button below the "Search" applet
in the top right of the page
.

Click this to open the "Online register search" page.
Here you may enter a doctor's surname and other details
to find information held by the Medical Council.

If you enter just "Blayney" (make sure you include the middle "y"), my name will appear.
