A re-enactment of the ship's arrival in 1913, bearing news of Scott's death in the Antarctic, is planned for February 10, and will begin with a dawn choral performance at Sumpter Wharf.
The choir, named Fly by Night, is made up of local men, who have been whipped into shape by professional singer Lynley Caldwell.
Ms Caldwell, who is a member of the Whitestone Community Arts Council, said although none of the 17 members of the choir were professional singers, she would still hold them to a ''high standard''.
''Members come from a wide variety of backgrounds. Teacher, radiologist, cabinet maker, baker, engineer, librarian, cleaner and theatre entrepreneur, to name a few.''
She said a range of ''appropriate'' songs would be sung on the day.
The choir has been in training for the 6am performance for the past two months.
Choir member Bill Blair said he particularly enjoyed the gospel harmonies, sea shanties and ''three-dimensional'' choral sound.
''It sends shivers up your spine.''
As part of Oamaru's Scott 100 commemoration events, Australian artist JuileePryor has gifted 80 hybrid-media panels to the Forrester Art Gallery.
The art work formed part of an exhibit which opened last Saturday.
Gallery exhibitions curator Alice Lake-Hammond said it was fitting
the ''90 Degrees South Again'' exhibition was part of commemorations.
''90 Degrees South Again acknowledges Scott's journey as a victory over death, recognising that despite perishing on the ice, the legacy of the expedition and its resulting research and photographic documentation, provide evidence of his success.''
Ms Pryor said her work had been ''heavily inspired'' by Waitaki old-boy and modernist Colin McCahon.
