His offending against the girl happened over a nine-year period in the 1990s, starting when the complainant was a child.
At the time of the offending, Foote was a deputy principal at an East Coast school.
He is no longer employed in schools.
After the verdicts were read out, Judge James Weir told the jury they may be interested to know that Foote had previously pleaded guilty in 2007 to 20 charges of possessing child pornography.
It was reported in February 2007 that Foote, who had been deputy principal of Lytton High School in Gisborne, was jailed for 10 months after downloading 1045 images on to a school laptop.
The images all involved sexual abuse of children, some as young as three.
The pornography also included images of sadism and bestiality.
Foote was granted leave to apply for home detention but in 2007 it was a decision for the parole board to make. It is not clear whether he was granted home detention.
Name suppression lapsed yesterday after Foote's lawyer Murray McKechnie said he would not be applying for it to continue.
He also did not apply for bail for Foote until sentencing.
The victim was in court along with her mother and other supporters when the verdicts were read out.
At least one of the jurors turned and smiled at the victim and her family as the jury left the courtroom.
The victim and her mother did not wish to comment on the verdicts.
Supporters of Foote were also in the public gallery.
Judge Weir remanded Foote in custody for sentencing on October 26.
