The son of missing New Zealand woman Linda Sidon has been arrested over her disappearance.

The arrest of the 28-year-old man comes a month after the investigation into Ms Sidon's 2009 disappearance from the Gold Coast was ramped up by police, and in the same week forensic officers began searching for evidence of the woman's blood.

The man is yet to be charged.
