Brian White opened his 2019 account just moments after entering the match for Bradley Wright-Phillips.
Making a run down the field, Kaku served in a lofty cross, which White dove for, heading it into the back of the net.
"We made eye contact, he played the ball in and I just tried to get my head on it," White said.
The 23-year-old from Flemington notched his second goal of his career, after scoring his first in 2018 at Red Bull Arena.
"We get to see day in and day out the work that Brian does," Head Coach Chris Armas said.
