The whānau of the kayaker last seen on Lake Rotorua six days ago has thanked those involved in searching for him.
Gregory Flavell, 18, went missing on Wednesday afternoon around 2-3pm while kayaking on the lake on the eastern side of Mokoia Island.
Navy divers using sonar equipment have been working at the lake but nothing of interest has been found.
On Sunday, police said the search would be reviewed and next steps considered.
Flavell's family thanked those who had looked for the teenager.
"Our whānau wish to express our huge appreciation to all the services and the many volunteers and whanau searching for him."
Flavell is Māori, approximately 6 foot 1 inches with shoulder-length wavy hair and has a light moustache and goatee.
He was wearing black cargo pants, a printed black long-sleeved T-shirt with the number 53 on the sleeve, and a dark blue beanie.
Anyone who may have seen Flavell or has details about him was asked to contact police on 105 and quote job number P051519937.
Earlier, police also appealed for information from occupants of any vessels that left Mokoia Island between 2pm and 5pm on Wednesday, August 10. Boaties were encouraged to contact Rotorua Police, either in person or via 105, if they did.
Police are seeking dashcam footage of the vehicle involved in the incident.
