Kate Bush, 25, was last seen wearing black trousers and a black "Mickey Mouse" hoodie.

Her 2011 red Toyota Yaris was found this morning in a car park near Lake Pupuke on the North Shore.

Police said they had been searching in the Lake Pupuke area today, and would continue to do so tomorrow.

Ms Bush's family and police have "significant" concerns for her welfare.

They are asking anyone who may have seen Ms Bush, or her car - registration number GER875 - in the last few days, to contact police immediately.
