New Zealand internationals Doug Bracewell and Jesse Ryder have been fined by New Zealand Cricket (NZC) for misconduct after a late-night drinking session.
The pair, neither of whom were selected for the opening Test against India in Auckland, were out until 3am in the morning.
NZC confirmed that the players have accepted a misconduct charge and paid fines of an undisclosed amount.
"The New Zealand selectors place great emphasis on qualities such as personal responsibility, trustworthiness and dependability - and will continue to do so with our encouragement," NZC Head of Cricket Operations Lindsay Crocker said.
"All players in contention for the BLACKCAPS need to satisfy the selectors of their commitment to prepare conscientiously for international fixtures."
While Bracewell was named in the squad before being left out in favour of Tim Southee, Trent Boult and Neil Wagner, Ryder was involved as a standby player with Ross Taylor's partner due to give birth shortly.

Ryder made a remarkable return to the game and played during the One-Day International series win over India less than a year after being attacked in Christchurch and suffering life-threatening injuries.
However, what is the latest in a series of off-field incidents appears to have thrown considerable doubt over his immediate international future.
Bracewell, like Ryder, does not boast of an impeccable record. In March last year, he was ruled out of matches against England after cutting his foot while cleaning up after a party.
New Zealand went on to win the first Test by 40 runs and will name their squad for the second game in Wellington shortly.
