Ms Macdonald, of MacTodd law firm in the resort, is also just the second woman in the South Island to have been granted a notary faculty - something traditionally awarded to a senior partner in a law firm.
Ms Macdonald, who became MacTodd's first female partner in 2002, received the appointment from the Lord Archbishop of Canterbury Justin Portal.
The resource management lawyer said it was a ''privilege'' to be granted notary public status and was significant for Queenstown given its international focus.
''Notaries can officially witness signatures on legal documents, administer oaths and certify the authenticity of documents usually for use overseas.
''With the increasing number of international visitors, and people taking up residence here, there is a growing call for notary services because a notary's signature is the only one that is recognised on the majority of documents for use in overseas jurisdictions.''
The other female notary public in the South Island is Julianne Hutton, based in Christchurch.
Otago now has 14 notary publics - four each in Dunedin and Wanaka, three in Oamaru, and five, including Ms Macdonald, in Queenstown.
