KEY POINTS:
A senior civil servant accused of raping a 13-year-old girl operated a system that awarded points to his victim for certain behaviour, a court has heard.
The 46-year-old was seen as a father figure by his victim, but came to form an "obsessional" relationship with the girl, who was of below-average intellect, isolated and "at times lonely", a High Court jury in Christchurch heard.
The man is on trial on three charges of raping the girl between June and November 2006. His name, occupation and the location of the alleged rapes are all suppressed.
