He said police had learned two cyclists had potentially been chased by dogs in the same area in Kaihu in November and December.
“We would really like to hear from those people – if this was you or you know who these people may have been please get in touch with us."
Pilmer thanked the people who had come forward since Te Rore’s death, saying they had provided valuable information.
Te Rore was the third person to be killed by dogs in Northland in the past four years, triggering calls for great action from local and central government to address the issue.
A service for Te Rore was held on Saturday, with many family and friends paying tribute to her via social media.
