Supporting participant quotes for the four key qualitative themes.

Theme	Supporting quote
Theme 1: Being part of a supportive groups who ‘gets it’	Our group was more established to help us work though our workplace difficulties and to help improve the emotional well‐being of staff members and allow them a safe place to communicate frustrations, concerns and struggles both in the workplace and personal. This was personally incredibly helpful personally as I have like‐minded people who acted as a sounding board who I knew had mutual respect and understanding. (Māori/6–10 yrs. service/21–29 y/o)
	Some of the more useful sessions stemmed from just checking in with each other…it was more about peer support than peer supervision. (16–20 yrs. service/40–49 y/o)
Theme 2: Time‐out to reflect on practice and problem solve	It is nice to share my experiences and problems and gain new insight into situations that I have trouble coping with or finding the best approach to manage a situation appropriately. (0–5 yrs. service, 21–29 y/o)
	This group has made me talk about myself more and my actions which would normally be ignored. I feel it has made me reflect on my practice more, and my interactions with staff. (6–10 yrs. service/21–29 y/o)
	I feel that I can take a bit of time to reflect on my practice before I go to peer support… having the peer support has made me aware there are other ways and to maybe seek a second opinion. (16–20 yrs. service/30–39 y/o)
Theme 3: Organisational barriers	Full attendance of my group is rare. Most months no one turns up. Mainly because patients are booked on the machines or work is over due [sic]. I feel peer supervision is not a priority and it should be. (16–20 yrs. service/40–49 y/o)
Theme 4: Group process issues Membership	Sometimes you have an issue with a member of your peer supervision group and it is hard to talk about within the peer supervision setting. I think it would be easier with a person who is an RT but not in your workplace. (6–10 yrs. service/21–29 y/o)
	The only thing I would like to improve is the trust issues. I have heard things come out of peer supervision which have been said in confidence. (16–20 yrs service/30–39 y/o)
Theme 4: Group process issues Structure	I have found that my peer group does not use the ground rules distributed as part of the peer group supervision project but have assimilated our own rules into our sessions. I feel that Peer Group Supervision in my group should probably be called Peer Group Support but all the same it has improved how I manage our patient workload which in turn must improve our patients experience in our centre. Therefore it has improved how I deal with patients albeit on a more strategic level as opposed to one on one interactions. (31+ yrs. of Service/50–59 y/o)
	I think our group would benefit from stronger leadership/facilitation as our last time was a real vent session – I do not feel that it was beneficial at all but it is difficult to communicate this to the group because I do not want to ‘put down’ the person who raised the issue. (16–20 yrs. service/30–39 y/o)
