The 14-year-old charged with dangerous driving causing death following a car crash in Masterton has been remanded for another four weeks.
The boy, whose name is automatically suppressed, is charged with causing the deaths of Featherston boys Hoani Korewha and Pacer Willacy-Scott, both 15, in the early morning of Sunday, January 31, after fleeing police.
He is also charged with dangerous driving causing the injury of another passenger, driving while forbidden, failing to stop and getting into a vehicle unlawfully.
He appeared in Youth Court yesterday and was remanded until March 23.
Yesterday two new charges, which lawyer Jock Blathwayt said were historic, were added to the mix, but details were not yet available on what they are.
The teenager is in the custody of Child, Youth and Family, and he was supported by family members during his brief appearance.
Mr Blathwayt said he had "not got to the point where we're able to ask for bail yet".
Judge Tony Walsh said he would allow at least half an hour for the hearing to go over details of the serious crash report, which has not yet been received.
The judge said the process had to be done carefully.
"The charges are very serious and it's only right that Mr Blathwayt has access to all that information."
