One of the teens accused of involvement in the death of Auckland schoolboy Stephen Dudley has pleaded guilty to a charge of assault.
He and another teenager were originally charged with the manslaughter of the 15-year-old, who died following a violent incident after a school rugby training session in June.
The pair, aged 16 and 18, appeared in the High Court at Auckland today where a two-week trial was set to begin.
The younger defendant pleaded guilty to an amended charge of assault and the trial for the co-accused was adjourned until June.
Both teens have had name suppression since charges were laid, after a judge ruled it would cause them "extreme hardship" to be named.
They were remanded on bail.
The 16-year-old will be sentenced next month when there will be further discussions over name suppression.
Justice Timothy Brewer did not enter a conviction, at the request of Lawyer Ron Mansfield, to "preserve the fullest range of sentencing options" for the teen.
