A win over College Old Boys this weekend would also give Metro the Broome Shield for winning the round robin Saturday competition. Metro already has the Evans Cup in the cabinet for winning the quickfire Friday night competition.
College Old Boys has bullocked its way into contention after beefing up a previous weak front row and against the odds beat the tough Feilding side 12-5 last weekend.
"College Old Boys are no slugs and we can't take them lightly this weekend," Gibson warned.
"Feilding are also very strong and stand a good chance at making the final."
Massey White, a team that has dominated the colts division winning every final over the last five or six seasons, languishes at the bottom of the table, yet still has a shot at gold with a return to form in the coming weeks.
In the meantime, a controlled whole team performance gave Metro a solid victory over Dannevirke last weekend.
"We had a pretty good game. It's always hard travelling to Dannevirke and beating them, but we played as a team and came away with a solid win. We ran them off their feet. Prop David Mariner had an outstanding game, while Desmond Tyrell had his usual controlled game at second five."
Gibson also singled out Mairangi Tamehana for praise.
"Normally Mairangi plays lock for us, but we put him in at first five at the weekend. He's a very good versatile player."
Feilding plays bottom of the table Old Boys Marist at the weekend, while Massey White take on Dannevirke.
