A local kaumatua performed a blessing of the Whairepo Lagoon area yesterday afternoon.
Meanwhile, rowers, paddle-boarders and members of the public were back enjoying the water this afternoon, Newstalk ZB reporter Devon Bolger said.
"I've seen some flowers in the water, presumably in honour of [Mayne], whose death is yet to be explained," she said.
Since the news of Mayne's death, friends, family and former colleagues from around the world have taken to social media to pay their respects.
Mayne, of Wellington, formerly worked for Transit New Zealand - which later became NZ Transport Agency - and as a personal assistant with the Ministry of Education.
Secretary of Education Iona Holsted said in a statement the ministry was "deeply saddened" by the news of Mayne's death and wanted to extend condolences to her friends, family and former colleagues.
"Sarah was a warm and caring person who was personally known to a great many people in the ministry and we are supporting staff who worked closely with her," she said.
Former colleagues called her a hard worker who had great relations with people throughout the office.
She has also been remembered for being loving and kind, and having a beautiful heart.
Anyone with information on her death can contact Wellington Police on (04) 381 2000 or call Crimestoppers anonymously on 0800 555 111.
