The phallic outline on flight radar would have had some plane spotters bemused.

A pilot took a penis-shaped flightpath over Auckland on Saturday in the name of cancer awareness.

The 50-kilometre stunt aimed to raise awareness about testicular cancer prevention through the launch of a new website goballsout.org.nz which went live on Monday morning.

The site encourages people to use their exercise tracking apps to create phallic "masterpieces".

Davis said Testicular Cancer NZ had seen him create an accidental penis during a flight in Wellington in October and asked if he could improve on it.

Vaughn created the phallic flight path by following a carefully planned GPS route using his four-seat Piper Arrow.

He said he had to get clearance from Whenuapai's military control tower to enter restricted airspace to complete the picture.

"I spent about 30 minutes on top of my usual pre-flight planning identifying a route that would give the desired result," Vaughn said.

There was no room for mistakes either.

"As my flight was tracked continuously by radar I had to make sure that I kept precisely to the planned track, any deviation would have shown up in the finished image."

The route went from above Orewa down to Piha, over part of the Tasman Sea and then back in from Muriwai.

Vaughn said he had no plans for any other unusual flights.

Testicular Cancer is the most common cancer affecting men between the ages of 15 and 39.

April is Testicular Cancer Awareness month.
