Crowds are expected to gather in Manawatu during ongoing search for missing woman Breanna Muriwai

Muriwai's mother Jasmin Gray posted on a traffic updates Facebook page, to warn commuters of delays and mass congestion on State Highway 1 in Sanson this morning.

She claims to have knowledge that her daughter's remains were in the area, and had organised a search supported by locals for information.

Muriwai was last seen in August 2022 at Te Horo Beach on the coast.
