Hamilton's Chartwell shopping centre has been cordoned off after several of what look to be "homemade explosive devices" were located.
"The NZDF Explosive Ordnance Disposal team has been advised and will be attending," a police statement said. "The roads around Chartwell mall have been cordoned off - Hukanui Rd, Lynden Ct and Comries Rd."
Nearby Hukanui Primary School has been placed into lockdown.
