A show home and a classroom were set alight in four "suspicious" fires over four hours south of Auckland last night.
Fire crews and police were called to the first fire at a Portacom on Hingaia Rd in Karaka at about 7.30pm.
A police spokeswoman said about 10pm they received reports a show home on McPherson Rd in Drury was extensively damaged by fire.
Emergency services were also later called to a classroom fire at Puni School at 10.37pm, and on Blake Rd in Puni growers crates were on fire at 11.40pm.
A Fire and Emergency NZ spokesman said the Puni School fire was contained to one classroom in a block of three.
