The Kaitaia CIB is challenging Kaitaia to help catch the person who robbed Coast 2 Coast bakery on Sunday morning.
Detective Sergeant Beatson said he believed the two women pictured above were the key to making an arrest.
"Someone will immediately recognise these two," he said.
"Obviously we want to speak with both women, and are asking anyone who can name them, or with any other information, to contact us urgently."
A Cantonese-speaking interpreter had been flown from Auckland, he added, and it wasn't until the victims were able to communicate in their native language that the full extent, and harrowing nature of their ordeal was realised.
