Zebo's current contract expires at the end of the season and the Ireland international has been linked with a move away in 2018.
Speaking at a press conference in quotes carried by the Rugby Paper to preview Munster's clash with Racing Metro in the Champions Cup this weekend, Zebo admits his long-term future is up in the air amid interest from France.
"I'm still deciding what I'm going to do in terms of my family and my future and it will probably take a little bit of time," he said.
"Munster is the creme de la creme when it comes to club rugby and I'm very happy to be spending my time here at the moment. If something changes or if I have a different motive for moving I'll see, but for now I'm just committed to playing as best I can on the pitch."
The full-back has been a top target for Pau, amongst others, in France and Zebo was candid when asked about the possibility of one day plying his trade in the Top 14.
"At some time in my career, it just depends when," he said. "It could be at any level or any time, but at some stage, yeah."
