After Ross sat School Certificate, Muriel decided to go to night school and passed School C English, then History the following year. Some years later she went to Rutherford College when they started taking adult students and obtained University Entrance. Several years later she returned to nursing (after 29 years), this time at Waitakere Hospital doing geriatric nursing (after a one week "on the job" re-introduction). She was instrumental in changing the "re-introduction" program for nurses returning to the craft. Muriel was just getting to really enjoy this when she injured her back lifting a patient and never recovered sufficiently to return to nursing.

Muriel always did considerable volunteer work including School Lunches, School Parent-Teacher committee, Scout Committee then following her inability to continue nursing , she became a volunteer for "Meals on Wheels" (7 years) and for 22 years volunteered for the New Lynn Citizens Advice Bureau, where the Management Committee noted her "willingness to do extra duties such as helping with publicity events, maintaining the roster, being the chief photographer, and doing housekeeping duties was especially appreciated..." A life of volunteer service continued with Hospice fundraising (4 years), and Volunteered at Titirangi's Lopdell House Upstairs Gallery.
