The All Blacks will be represented at Lochore's funeral by mental skills coach Gilbert Enoka who will make the trip back from Perth to attend on the team's behalf.
"That's going to be a special thing for us," Foster said of being represented at Lochore's funeral.
"He's a very special human being. Forget about a rugby man, he's a very special human being. There's a massive sense of loss in the team. Even for those who didn't know him, you kind of feel like you did.
"Just the humility and humbleness — he's done himself and his family immensely proud with his life and we're all hurting for it."
The 78-year-old Lochore played 25 tests (68 matches) for New Zealand at No 8 and lock from 1964 to 1971 and is survived by his wife, Lady Pam, their children David, Joanne and Sandra, and their eight grandchildren.
Lady Pam and the couple's children said they were mourning, but relieved his suffering had ended. They wanted to express their gratitude for the care and support the family has received since Lochore's diagnosis.
