This should also happen when you log in a tty.

It was reported [1] and documented in the wiki [2]. zprofile sources
/etc/profile,
which replaces your $PATH ignoring already existing settings. What I did was
modify /etc/profile to include the value of PATH in the newly created variable:
PATH="$PATH:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"
