Trade Me's head of policy and compliance, James Ryan, said the report reinforced the company's commitment to transparency and gave customers an insight into how it responded to requests for their data.
"The recent global attention on data sharing has heightened public awareness around privacy, and New Zealand consumers have a right to know how their data is being shared."
He said the requests relating to homicide or missing persons were to do with trying to locate someone's whereabouts.
Not all requests by police were successful with one in four resulting in no release of data.
Ryan said Trade Me worked hard to release only relevant and necessary information.
"We only release information when it's legally requested of us, and we're satisfied it's appropriate. If we feel a request is too broad or insufficient, we push back, and we did that 22 times last year," he said.
A police media spokeswoman said the New Zealand Police conducted a wide range of investigations into criminal conduct.
"Police may request the assistance of companies who hold information that will assist in our inquiries," the spokeswoman said.
"We continue to have a strong working relationship with Trade Me, and value the continued work they are doing to prevent people in our community from becoming victims of crime."
