Police have charged two men after raids in Hawke's Bay uncovered methamphetamine, cocaine, cannabis, ammunition and a large amount of cash.
The searches were carried out at properties in Wairoa and Raupunga under warrant. The operation led to charges against an 18-year-old and a 24-year-old, who face allegations of drug supply and unlawful possession of ammunition.
Both men will appear in Gisborne District Court on Friday. Police also arrested two other people on outstanding warrants during the operation.
Police said more arrests are expected as the investigation continues.
