Ms Sutton said DOC's national policy for New Zealand fur seal responses is minimum intervention to avoid stressing the animal, unless they are in obvious trouble.
"We will only respond to reports of seals that are at risk of being harmed or causing harm, or are seriously injured," she said. "It is common to see seals resting on shore for long periods of time. They may be immobile for long periods, or look as if they are crying, sneezing or coughing. This is all typical behaviour for seals."
Although they are marine mammals, kekeno spend a lot of time on land. They need to come ashore to rest.
They may look harmless but seals can move very quickly if they feel threatened and they bite.
Ms Sutton said it was best to stay at least 20m away and not to get between them and the sea.
"Do not try to move a seal or pick it up and take it home," she said.
People can report seal and other marine mammal sightings using an online form on the DOC website: www.doc.govt.nz/nature/native-animals/marine-mammals/seals/
Filling in this form helps DOC look after marine mammals by providing information about population sizes, breeding rates and movement patterns.
If you come across a seal that has been injured, or one that is in danger of being harmed, call the DOC hotline on 0800 362 468.
