A group of youths were robbed at gunpoint as they made their way home along a Napier street early on Wednesday.
Detective Sergeant Emmet Lynch, of the CIB, Napier, said police had been told the incident happened on Latham St, near the main McLean Park carpark, about 1am.
Two men in a light grey early 2000s Falcon with a spoiler on the rear, had parked on the "wrong" side of the road near the youths.
The passenger had a firearm and demanded the youths hand over their cellphones and money.
The robbers then got out of the vehicle and searched each of the youths, stealing additional items.
Both of the robbers were described as male Maori.
One was thought to be aged in his 30s, about 1.76m in height, of stocky build, with very short black hair, and wearing a red T-shirt and black pants, Mr Lynch said.
The other was younger, slightly taller, of solid build, with black medium-length hair and wearing a red cap, red-and-black basketball singlet and black shorts.
Mr Lynch said several vehicles and people had passed the scene while the robbery was happening.
Police wanted to speak to anyone who could help with their inquiries.
Aggravated robbery, which includes robbery with a weapon or robbery by two or more people, carries a maximum prison sentence of 14 years.
