Thanks!
I enabled a2enmod and restarted apache, added
<Directory “/var/www/html”>
AllowOverride All
</Directory>

to the 000-default.conf file, and then finally added,

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} =staff.domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/wp-admin/$1 [r=301,nc]

restarted apache and Bingo!
Thanks again Mindctrl
