A man's attempts to flush drugs down his toilet during a police raid were foiled because the system was already blocked by electronic scales.
Hamilton police said they were "flushed with success" after officers stopped the 32-year-old man disposing of what is believed to be methamphetamine.
He had been trying to dispose "of a large quantity of what is believed to be methamphetamine when he blocked a toilet with a pair of electronic scales", Senior Sergeant Freda Grace said.
Armed police were involved in the search of the Fairfield home yesterday.
"Quite often when dealing with offenders involved with drugs our staff encounter people armed with a variety of weapons and in yesterday's case two imitation firearms were recovered," Ms Grace said.
She said as well as the drugs, a "sizeable amount of cash" had also been seized from the home.
A man has been charged with possession of methamphetamine for supply and breach of bail charges and was due to appear in the Hamilton District Court today.
