IAG-owned insurer AMI has warned homeowners after data showed water heating system thefts lead to the costliest burglary claims in New Zealand.

It says more than 500 water heating units a year are stolen from homes, with some claims related to the thefts exceeding $NZ200,000 ($182,684).

“These essential household systems are incurring extensive damage to homes when being stolen, particularly due to flooding,” AMI consumer brands EGM Paula ter Brake said.

Ms ter Brake says water heaters are commonly stolen for their resale value, with copper pipes and gutters also targeted. 

She says exterior units can be taken without setting off security alarms.

“To onlookers or neighbouring residents, thieves may also appear to be carrying out work on properties when disconnecting these units.”

The insurer recommends homeowners disguise their water systems and has suggested replacing copper pipes or having them painted over to reduce their allure.

AMI says burglary claims have remained high following a record number in 2022, with the most common time of theft the early afternoon.

“Our data shows windows are the most common entry point for burglars, which contributes to repair costs,” Ms ter Brake said. “Glass panels are frequently smashed, and surrounding furniture often sustains malicious damage.” 

The Auckland and Canterbury regions have the highest rates of house burglary claims, accounting for a combined 54.7% of New Zealand’s total. 

Clothing and shoes are the most commonly stolen items, followed by electronics, power tools, gardening equipment, bikes and sunglasses.
