New Zealand players Jesse Ryder and Doug Bracewell are under investigation after visiting a bar on the eve of the first Test against India in Auckland. A release from NZC said the board would investigate the incident over the next few days.

Mike Sandle, New Zealand's manager, said the players had confirmed they were out at a bar until early hours on Thursday morning and added he was disappointed by the incident.

"Their behaviour is totally unacceptable the night before a match," Sandle said. "We trust the players to make good decisions and the pair have breached this trust."

Bracewell and Ryder were both part of the Test squad with Ryder being picked as a back-up for Ross Taylor, whose second child is expected during the Test series. Both players were not part of the playing XI for the first Test and were released to play for their respective first-class teams in the Plunket Shield. Bracewell, however, was ruled out of the Central Districts match after suffering a foot injury.

Bracewell and Ryder had earlier faced disciplinary issues during the series against South Africa in March 2012. Both players were dropped from the ODI team after breaking team protocol, following the match in Napier. In November last year, Bracewell was dropped from the Central Districts side for an HRV Cup game after a late night out.

The ODI against South Africa in Napier in March 2012 was also the last match Ryder played for New Zealand until his recent comeback against West Indies. Following the incident, the batsman, who has had disciplinary issues in the past, decided to take an indefinite break from cricket. In March 2013, Ryder was assaulted outside a bar in Christchurch and spent two days in a medically induced coma before making a recovery. In August 2013, he was given a retrospective, six-month ban for failing a routine drug test while playing domestic cricket.
