Hi John, from the below it doesn't sound like it should be that difficult, have you tried to contact the Company Secretary.
" 3. Loss of Share Certificate
In a situation where a shareholder informs the company that he or she has lost the Share Certificate, the company secretary will need to prepare the following documentation:-
DRIW noting the loss of Share Certificate and confirming that the previous Share Certificate is now void
Preparation of new Share Certificate
Thereafter, the company secretary will update the relevant registers to cancel the old Share Certificate and replace it with the new one."
