Detective Sergeant Mark James, of the Hamilton police crime investigation unit, said officers raided a home in Kenna Avenue at 6am Wednesday.

They located about three grams of crystal methylamphetamines, $300 in cash, mobile phones and drug paraphernalia.

Detective Sergeant James said there was evidence on the phones of drug trafficking.

Louise Milgate, 41, of Kenna Avenue, was arrested, interviewed, charged and appeared in the Hamilton Magistrates Court on Wednesday.

She unsuccessfully applied for bail and was remanded in custody to appear in court again for a mention hearing on December 19.

Ms Milgate was already on bail after being charged in July with trafficking 50 grams of ice, valued at an estimated $25,000.

Detective Sergeant James said police believed that Ms Milgate had continued to use and traffic drugs.

Two search warrants were conducted between her first arrest and Wednesday which resulted in police coming up empty-handed.

"It's just another sad story of someone getting into drugs, particularly methamphetamine, using and turning to drug dealing," he said.

"She has no criminal prior court appearances and is now facing a term of imprisonment," he said.
