About 400 people have filled a Christchurch church this afternoon to farewell Diana, Lady Isaac.
The funeral for the respected conservationist and businesswoman is under way at the Church of St Michael and All Angels in Oxford Tce. Bishop Victoria Matthews is officiating.
Isaac, 91, died at her home in Christchurch on Friday.
Speaking this week, Rob Clarke, co-trustee of The Isaac Conservation Wildlife Trust, said the public service would be a respectful occasion for "a remarkable woman".
Clarke said the charitable trust would "continue indefinitely".
"One of the last things she said [to me] was she just wanted everything to continue as it was currently, " he said.
Isaac's niece, Catherine Isaac, said her aunt's death marked "a big milestone" for the family, as she was the last surviving member of her generation.
Her aunt was a private person but adored by all who knew her.
Prime Minister John Key said Isaac's contributions to New Zealand were "truly remarkable".
