While a knock of 45 isn't cause to declare that New Zealand's opening batting woes have been solved, Flynn said he could see himself settling in to the job.
"I'd like to think so. It's a challenge that I enjoy," he said. "I haven't had a lot of experience at it, but getting out there is something that I've enjoyed."
Flynn will undoubtedly get another crack with the bat on day five today depending on when South Africa choose to declare their second innings.
They closed day four on 75-0, with a lead of 274 and are in complete control of the game with openers Graeme Smith (34) and Alviro Petersen (38) unbeaten at the crease.
New Zealand will have to either bat out the day or have a dig at a fourth-innings run chase without their captain and most accomplished test batsman, Ross Taylor. The right-hander copped a Morne Morkel bouncer on his left forearm shortly after lunch yesterday and was forced to retire hurt on 18. X-rays revealed a fracture to Taylor's ulna bone in his forearm and it is highly unlikely he will play any further part in the test.
New Zealand assistant coach Trent Woodhill said the side wanted to put in a fourth-innings batting display their skipper would be proud of.
