Staff working on a key project to modernise the court system were compelled to work evenings and weekends to try to keep the $30 million task on track.
The extra hours were intended to "break the back" of the project after a series of delays and were piled on as managers were told the Electronic Operating Model project would be "no Novopay".
But whatever time was saved was soon at risk when the Ministry of Justice found itself beset by a wave of resignations from the project team.
Details of the project were released under the Official Information Act. They show it is behind schedule and on track to exceed its budget - although the exact amount of excess spending is still unclear.
The EOM project is on the radar of Government chief information officer Colin McDonald, recently appointed to oversee state IT projects in the wake of the Novopay meltdown. A spokeswoman said Mr McDonald had been assigned oversight of the project and was aware of issues arising from it.
