A Rotorua woman has admitted sending threatening texts to herself in a bid to get her former boyfriend into trouble.

Jacinta Maree Hammond, 23, used a pre-pay phone to send the texts to her phone and then a few weeks later told police they were from her estranged partner, the Rotorua Daily Post reported.

She pleaded guilty to charges of making a false statement to police and wilfully attempting to pervert the course of justice when she appeared in Rotorua District Court this week.

Judge Phillip Cooper remanded Hammond on bail for a pre-sentence report and sentencing on July 19.
