The chief executive of the Sir Edmund Hillary Outdoor Pursuits Centre, Dr Grant Davidson, said Ms Sullivan had not made any decisions about her future. An internal investigation into the accident, the result of which would be made public, had begun.
"At this stage we think it's wise just to give her some time to get herself and things together ... she has been incredibly brave in dealing with this.
"She's as okay as anybody in her situation could be but she's obviously still feeling immense grief."
Ms Sullivan, who had been in the job for three months and had gained experience in similar roles overseas, drew praise from Dr Davidson for attending the funerals.
"I think it shows a lot of courage and integrity."
He said OPC staff had "suffered quite heavily" and had counselling sessions this week in dealing with the organisation's worst tragedy.
Meanwhile, the rahui (temporary ban on activities) placed on the Mangatepopo River remains, despite the OPC opening its doors again to groups last Sunday. Dr Davidson said the lifting of the rahui was "a matter for the tangata whenua to decide".
"But my belief is that at some stage in the near future the parents will be visiting the site.
"It won't be until after that that anything happens."
