Meredith came off the bench at half time at the County Ground to make his first appearance for City since New Year's Day after breaking a bone in his foot back in January.
Although usually a left back, the Australian actually came on in central midfield at the start of the second period following an injury to Nathan Doyle.
Parkinson said: "It was great for Mez (James Meredith) just to be back out on the pitch.
"As I said on Friday, I wanted to give James some game-time between now and the end of the season. I've put him on the bench today (Monday) with the aim of probably giving him twenty minutes or so at the end, but he's played 45 minutes instead.
"He's come through with no ill effects which is clearly good for him.
"It is definitely a positive for us to have Mez back."
Meredith was introduced for Doyle at the interval when the midfielder tweaked his groin slightly in the first half after having problems in that area recently.
Parkinson added: "It is a problem he has had for a while.
"We always knew that going into today's game would be tough for him after playing on Friday as well but Matty Dolan had a tight groin and we had to leave him out.
"Doyle's problem is something that ideally requires him to have rest after games - he certainly hasn't been training a lot lately.
"If Matty had of been 100%, we probably wouldn't have started Nathan anyway.
"That is the way it goes sometimes, and credit to Nathan because he put his hand up to play as well.
"Unfortunately he just over-stretched in the first half and he was in a lot of discomfort at half time.
"We want to get him through to the end of the season now and then he'll see a specialist to see whether he might need a small operation to clear the injury up."
