Police said the ute stopped and then appeared to attempt to deliberately ram the patrol vehicle before leaving.
A pursuit began but was abandoned less than a minute later due to the manner of driving.
Police said the ute then attempted to ram the same patrol vehicle again as it drove away.
The Eagle helicopter was deployed from Auckland to help and located the empty vehicle at a Kaingaroa Forest property just before 12.30pm.
Police are continuing to make inquiries to identify and locate the person involved.
Police would like anyone who witnessed a silver-coloured Ford Ranger ute in the Kaingaroa Forest area today to contact Police on the 105 number and quote the event number P043468128.
Alternatively, anonymous information can be given through Crimestoppers on 0800 555 111.
