The 26-year-old who has been speaking with Police in relation to the disappearance of Grace Millane will be charged with her murder.
He will remain in Police custody until Monday morning when he will appear in the Auckland District Court.
The 26-year-old is the same man who was questioned previously by police and was with Ms Millane at several places, including Sky City, before going to CityLife Hotel with her.
"The Millane family have requested privacy at this time and will not be making any further statements at this stage." said a Police spokesperson.
