Charges are to be laid against in Auckland District Court on Wednesday in relation to a home invasion in the suburb of Epsom a week ago.
A 62-year-old man and his 29-year-old son were badly beaten by three men shortly after 5am last Wednesday.
A 19-year-old faces a charge of aggravated burglary and two charges of aggravated wounding.
A second man, a 20-year-old from Manukau, is facing the same charges.
Police are still looking for a third person, Cameron Geros, 17, who is known to have connections in Northland.
The 62-year old victim is still in hospital with a broken back, lacerations and multiple facial fractures.
Investigators believe he was run over in a stolen car as the offenders left the scene.
