Community volunteer Elsie Dixon paid tribute to the two officers and said their deaths would not be in vain.
She said Hattersley was a "community in mourning" adding: "Those two girls are precious.
"We are a community that care, not just for ourselves but for each other and for the people that serve our community.
"Our police officers are part of our community and those girls were special."
She said: "Yes, we are hurting. But the families, friends and colleagues of those two young lasses are hurting a damn sight more."
Struggling to compose herself Mrs Dixon added: "Our hearts are overflowing with tears.
"As many rain drops as you see, as many petals as you see on the flowers. Those tears are within each of our hearts."
As she finished her speech she was given a hug and kissed on the head by Mr Adderley who thanked her for her words.
The Reverend James Halstead said a prayer for the murdered policewomen and their families.
Addressing the crowd, Sir Peter described GMP as "one big family".
He added: "We have lost two members of our family and we feel that loss very, very deeply."
He said the force and the families of the women had been "hugely moved and uplifted" by the support shown by the public in the local community, Manchester and around the world.
"We treasure the memory of Fiona and Nicola," he added saying their "great service" symbolised the work done by police officers day in, day out.
After the ten minute vigil was over many people gathered around the large number of floral tributes to leave their own flowers and read the cards and messages.
