I have a set of x & y data points in one list;

xydata={{x1,y1},{x2,y2},{x3,y3},{x4,y4}};

and a corresponding set of z data points in another list:

zdata={z1,z2,z3,z4};

I wish to combine them into one list of {x,y,z} data points,
which I can do by:

{temp1,temp2}=Transpose[xydata];
xyzdata=Transpose[{temp1,temp2,zdata}]

which gives the desired result:

{{x1,y1,z1},{x2,y2,z2},{x3,y3,z3},{x4,y4,z4}}

QUESTION:  Is there a more efficient way of doing this?

Thank you.
