The parlour guitar had been a gift from him to his wife, Bernadette Moroney.
And one mandolin had been handmade by a Dunedin friend and instrument maker Steve Barkman.
Mr Moroney is a member of musical groups The Chaps and Catgut and Steel and is president of the New Edinburgh Folk Club.
He hoped that whoever had taken the items was ultimately "stopped in their tracks" by the police, to prevent the same thing happening to other people.
It was "not the end of the world" and he would still be able to perform music, but the situation was "frustrating" and distressing.
On the other hand, he had been "overwhelmed" by a huge amount of support from fellow musicians all over the city, who had been emailing him and contacting him via social media since they heard his instruments were gone.
