Police are investigating a number of possible sightings of missing Christchurch woman Yoon Sook Chun.
Six years on from her disappearance, police are offering a $30,000 reward for fresh information that might help find her.
Since the appeal last week, Detective Sergeant Ross Tarawhiti said around 10 people had phoned in claiming to have seen the missing woman.
Those sightings are yet to be confirmed.
Yoon Sook Chun went missing from the Aidanfield suburb of Christchurch in 2009, after emailing her family saying she was going to Auckland for a break.
