A Taupo teenager has admitted to seriously injuring two cyclists after his father had ordered him to drive on a revoked licence.

Jordan Lee Dobbyn, 17, appeared at Taupo District Court today on two charges of careless driving causing injury and one charge of driving while his licence was revoked.

Dobbyn pleaded guilty to the careless driving charges and not guilty to driving on a revoked licence.

Two cyclists, David Joyce and Sirpa Lijunen, of Kinloch, were riding along Poihipi Road, 10 km west of Taupo, on May 25 when they were hit from behind by Dobbyn who was driving his father's Toyota Hilux back to the family farm on Tuhingamata Road.

Ms Lijunen spent several months recuperating in Waikato Hospital from injuries including fractured vertebrae, deep lacerations and internal bleeding.

Mr Joyce was also hospitalised with broken vertebrae and shoulder blade, and a deep 15 centimetre cut to his buttock.

The couple have had on-going treatment to rehabilitate from their injuries .

Jordan Dobbyn told police he had been ordered by his father, Timothy Dobbyn, to  drive the Hilux and was following his father as he turned into Poihipi Road from Whangamata Road, near Kinloch.

The cyclists were travelling in the same direction along Poihipi Road and near the fog line when they were hit by Jordan Dobbyn, a summary of facts said.

Dobbyn said he saw his father pull out into the middle of the road and then heard a "bang".

He told police he did not see the cyclists.

Dobbyn was remanded on bail on the careless driving charges for sentencing at Taupo District Court in October.

A hearing date would be set on the same day for the charge of driving on a revoked licence.

Timothy Dobbyn has previously appeared charged with counselling his son to drive on a revoked licence.

He has been remanded for callover in Taupo District Court in October to set a defended hearing date.
