They competed in the annual clocktower race - none managing to beat the chimes - tested their bodies with a Les Mills body attack class and got competitive in a rousing game of musical chairs.
Jack Montgomerie (18) was glad the planned abseiling event was cancelled as "it would have been terrifying".
At the end of the fourth day, he had not had enough of the competition but was "really tired" after participating in other Orientation events in the evenings.
The winner of the Fresher Competition will be announced today after the group competes in an inflatable games event, participates in another Les Mills fitness class and passes the exotic food challenge.
The top competitor will receive a prize package for an adventure weekend getaway to Queenstown consisting of free car hire, food and accommodation, and passes for paragliding, river surfing, bungy jumping, a canyon swing and a Shotover Jet ride.
He or she will also receive an iPod, an Xbox, a bicycle, a Coronet Peak ski pass, two Highlanders season passes, movie tickets, a massage and a sauna.
