Another rugby-playing Guildford is in trouble for alcohol-related offending.

While former All Black Zac Guildford awaited the decision of a misconduct hearing, his cousin Levi Guildford, 19, faced a drink-driving charge in Hawke's Bay.

Levi, 19, has been charged with driving with a breath alcohol reading of 719 micrograms of alcohol per litre of breath. There is a zero alcohol limit for drivers under 20.

Police allege he was driving in Bledisloe Rd, Napier, about midnight on Saturday when he was pulled over at a checkpoint.

He will appear in the Napier District Court later this month.

Levi Guildford, who plays at No 8, was in the New Zealand and Hurricanes Schools teams in 2011 and was named in the 47-strong New Zealand under-20 training squad last year.

Hawke's Bay Rugby Union chief executive Mike Bishop said yesterday that he was unaware of the charge.

"I would need a bit of evidence before I did anything formal about it," he said.

"Obviously I will be talking to the coaches and see what they know about it."

He said Levi was one of about 50 players in a Hawke's Bay training squad preparing for the upcoming club rugby season.

He was not in the provincial team, "but if he keeps training and improving the way he is, he probably will be one day".

Zac Guildford, 24, faced a misconduct hearing at the NZ Rugby Union on Tuesday night for allegedly assaulting a partygoer in Christchurch in January.

The NZRU is expected to announce today that he has been cleared to resume playing for the Crusaders.

He had voluntarily stood down from the team, pending the hearing.
