The nurse was giving evidence in the retrial of George Gwaze, 60, who is being retried at the High Court in Christchurch on charges of sexual violation and murder of his niece Charlene Makaza in January 2007.
The defence says the girl died from severe toxic shock brought about by an HIV infection she had carried since birth.
The Crown says she suffered a forceful sexual attack by her uncle.
Shannon Brophy, a nurse at the 24 Hour Surgery on Bealey Avenue said Mr Gwaze drove to the entrance of the clinic and asked for help while his wife Sifiso helped carry Miss Makaza inside.
Earlier, an elder of the church the Gwaze family attended, Musa Masenda, said the 10-year-old appeared noticeably unwell at church the day before she died.
Mrs Masenda said she appeared breathless, had a limp and kept wiping her mouth.
When asked how she was, the girl told Mrs Masenda she had a headache and thought she was getting a cold. Mrs Masenda says she prayed for the child's health that evening.
