How to change file permission of error.log and access.log

Is there a way to change the file permission of access.log and
error.log?
Currently nginx is creating file in user readable and writable mode.
I want those files to be readable by group.

Only with external tools. nginx has no such settings and you could not
use umask either, because nginx call umaks(0) on start.
