Whyatt tried to stop police arresting her partner and pulled the female officer away.
Asked to leave and pushed away by police, Whyatt kicked the female officer in the head, grazing her face, before she "continued to dance" and avoid arrest.
Judge Jonathan Down said at court yesterday: "This is a bit out of the blue, isn't it?"
The duty solicitor, representing Whyatt and Burton, said the incident was a case of "far too much alcohol" being consumed.
The couple's lawyer said Whyatt was prepared to pay a donation to the police fund.
Judge Down discharged the third year EIT health student on the charges of obstructing and resisting police but convicted her of assault and ordered her to pay $300 in compensation to the female officer and $130 in court costs.
Burton was convicted of assault and ordered to pay $300 to the officer he punched, a $250 fine and $150 in court costs. He was convicted and discharged on the counts of obstructing and resisting police. Burton has apologised to the officer he struck.
