Abano Healthcare Group sees no justification in changing what it says is a legally valid date for its special meeting on June 13.
The group, which includes Lumino The Dentist, is facing a divisive vote following a move by dissident shareholders to remove chairman Trevor Janes.
On Friday, one of the shareholders, James Reeves, filed proceedings in the High Court seeking orders to postpone the special meeting to a date three to four weeks after June 13.
Abano Healthcare Group managing director Alan Clarke said the Abano group saw no justification in changing the date for that meeting.
Abano gave notice of the special meeting on May 23. The NZX approved the special meeting on May 21, followed by the posting of the notice of meeting to all shareholders on May 23.
The notice of meeting provided 13 working days' notice for a special meeting, exceeding the 10 working days required under Companies Act provisions.
In parallel, Michael Timoney, the former chief executive of Dental Partners Pty, Abano's Australian dental subsidiary, served a claim for $A4.5 million ($NZ4.9 million) in relation to his termination early last year.
''Abano sees no merit and will strongly defend this claim,'' Mr Clarke said.
