Police will apply for a fresh apprehended violence order against Salim Mehajer on behalf of his estranged wife Aysha, in the latest court battle for the property developer and former local councillor.

NSW Police confirmed on Tuesday a new application would be made on August 9 in Sutherland Local Court.

Police applied for an interim AVO against Mr Mehajer on behalf of his estranged wife in July last year, less than a year after the couple's lavish wedding in August 2015.

The order prevented Mr Mehajer, the former deputy mayor of the now-defunct Auburn Council, contacting or approaching Ms Mehajer.
