"The extremely hazardous terrain in the search area has seen a large amount of rainfall, which means conditions are still not safe.
"Plans to resume searching are ongoing."
When the search does begin again it will include extra resources including search dogs.
"It is expected that when the search resumes, it will involve specialist trackers, search dogs, and the use of RECCO search radar, once conditions are dry enough."
O'Connor, who worked at Abel Tasman Kayaks, knew the area well and described herself as "passionate about nature and working in the outdoors" on the company's website.
"I'm proud of the fact that I'm doing what I love to do every day."
