In March, he was the victim of an assault that left him in hospital in Christchurch in an induced coma.
Klee said a return to international cricket was hopefully not too far away for Ryder.
"He's going to need to perform, firstly. We all want to see some consistency and stability from him.
"He met with Mike Hesson for a good talk last week. We've maintained communication with the Black Caps right through this hiatus.
"At some point, Jesse needs to get back into international cricket. He just needed some time to sort himself out.
"We're getting close to that point. After what happened in Christchurch, we realised there wasn't much point sitting around. It's time to get back on the horse and get the career charging again.
"All going well, it won't take him that long to get back into international cricket.''
Ryder was making good progress, Klee said. There were a couple of lingering concussion issues, but specialists had advised that was to be expected.
Ryder had been working hard on his fitness and was ``probably in better shape than he was at the end of last season''.
