Going into the match with a 1-0 advantage from the first leg a fortnight ago, the Princesses scored twice in the second half to qualify on 3-0 aggregate to the final round of the qualifier where they are scheduled to play Ethiopia over two legs to book a place in the finals in Papua New Guinea.
Niber-Lawrence who was unmarked out-jumped her markers to head home from an incisive cross from Wasila Soale who profited from a counter-attack after the homers turned defence into attack having survived a rear invasion from the visitors.
Guinea after conceding quickly regrouped and the results was a tightened defence to keep at bay the attacks from the slippery Ghanaian with Rita Obiang and Crisanta Nguema emerging exceptional in their respective roles.
Just when it appeared the visitors had found an antidote to the Princesses' onslaught, substitute Veronica Appiah, beat an offside trap to fetch Ghana's second goal on the stroke of time. The striker darted free to beat the trap and unleashed a thunderbolt to beat advancing goalie, Lucia Andeme to wrap up victory.
