A Year 13 pupil kept in Dunedin Hospital overnight for observation after a swimming excursion mishap near Purakaunui on Friday is expected to be back at Columba College today.
Board of governors chairman Tony Sycamore said the pupil was discharged on Saturday and was doing well. He understood she would be back at school today.
''Getting her released [on Saturday] was something we were all really delighted about,'' he said.
She was one of seven pupils taken to hospital after the swimming trip went badly wrong, and the only one kept in overnight.
About 18 pupils were rescued from a rip off Canoe Beach by three surfers, and surf live-savers who were practising at nearby Warrington for the South Island IRB (rescue boat) championships.
Mr Sycamore said the school's immediate focus was ensuring those involved were supported.
''The major thing over the weekend for us has been in getting as much care and support around the people involved as possible.''
An investigation of the incident would be thorough. It would be ''irresponsible'' to predetermine the outcome, he said.
Told Surf Life Saving New Zealand planned to contact the school, Mr Sycamore said he welcomed that, as well as liaising with other concerned parties.
''If that offer is there, fantastic. We'd be really grateful for any input at all.''
The ''unspoken heroes'' of the day were the teachers while the pupils' response to the event was also commendable.
''The way they have dealt with something that was completely out of the blue is just so impressive,'' he said.
In an email to parents on Saturday, Columba principal Elizabeth Wilson said the school was proud of the fact pupils pulled together, and the way staff managed the situation.
She asked pupils to respect other students' privacy when discussing what had happened.
''It's natural for students to discuss what happened on social media but we would like to remind students that social media is often public and that this is a difficult time for those involved and they should be mindful of respecting the privacy of other students and staff.''
Surf Life Saving New Zealand Otago club development officer Steph Laughton said, when contacted, she was keen for the organisation to visit Columba College to see how they could work together.
Most Dunedin schools liaised with the organisation before taking pupils swimming in the sea, but that had not happened in this instance.
