"I came back to grab some things over easter and noticed the safe had been stolen. I couldn't believe it. I spent 11 years training for two national surf lifesaving competitions in Gisborne and Dunedin. When the medals were taken I felt like a piece of me had gone. I was really, really angry and just wanted to hit someone," Mr Horwell said.
Detective Senior Sergeant Parnell said jewellery and tradesmen's tools are the most common items being stolen.
"Jewellery is a hot commodity for a would be crook to get rid of on the black market. Building materials including pink batts, copper spouting, kitchens, hot water cylinders and other items in homes scheduled for demolition are also being targeted. It's a wheel that doesn't stop rolling. People need to be cautious," he said.
Mr Horwell said when you leave things in your own home while it's being repaired, you don't expect anything to be taken.
"Whoever did this, has some nerve. There is nothing we can do but these items have no sentimental value to anyone else apart from my wife and I. We just want our belongings back," he said.
Detective Senior Sergeant Parnell urged people to take all their valuable items with them if they are moving out temporarily and also advised tradesmen to be safety conscious and take their tools with them, instead of leaving them on-site.
