How to filter certain points out of a 3D point cloud?

I got a 3D point cloud which is already in the world coordinate system. I got the data from a Kinect sensor. As I want to build an occupancy grid out of the data, I need to filter out all points with Z=0. I need to do this because Z is the vertical and if Z = 0, there is no obstacle on the way. To get the point cloud I used
xyzPoints = depthToPointCloud(depthImage,depthDevice);
So in the end I want to have just the points left I can plot into the 2D grid.
Thank you very much for any help!
