Recent hot, dry conditions mean that fires which are deliberately lit have the potential to spread to nearby properties, putting lives at risk.
Police in Counties Manukau East are investigating a spate of arson attacks carried out in the East Auckland area since the beginning of 2015.
Detective Sergeant Glenn Wilkinson of Ormiston CIB says that 11 scrub fires have been lit in the Howick area since January.
"These have occurred in local
reserves and children's play areas, usually bordering residential houses," says Detective Sergeant Wilkinson.
"On each occasion they have been set between 6pm and 11pm."
Police note that the Fire Service indicates that there has been an increase in small arsons across the District, however the East Auckland area including Pigeon Mountain, Bucklands Beach and Musick Point have seen a particular increase.
