The role was created to enable the organisation to place more emphasis on lobbying the Welsh Assembly over healthcare policy.
The move follows an announcement earlier this year that an extra £32m is to be made available to the NHS in Wales to help reduce waiting lists.
Despite recent reductions in the number of people on NHS waiting lists in the country, patients in Wales still have to wait longer for treatment than those in England. Davies said he wanted Welsh nurses to play a greater role in healthcare provision and planning.
'Nurses feel they can do more than they are being asked to do,' he added.
'Their capabilities are not being fully exploited and they are an untapped resource.'
Davies will also try to strengthen the organisation's profile in Welsh publications and newspapers. As the only Welsh speaker in the press office, he will be able to provide more interviews in the national tongue.
Reporting to director Tina Donnelly, he leads a four-strong team.
