Whanganui's Hells Angels headquarters may be getting a little extra traffic this week as Pokemon Go players show up for their free pokeballs.

The popular app has players move around in real life to move an avatar on their phone screen, and has them travelling to different areas to catch Pokemon.

Some landmarks and monuments are designated as "pokestops", where players can pick up items such as pokeballs, eggs, and potions.

Players have discovered that the Whanganui Hells Angels pad on Kaikokopu Rd, Aramoho has been set down as a pokestop, a fact that has gained attention on Facebook.

A post about it on Facebook page Only In New Zealand has so far received more than 5000 likes, and more than 1000 comments.

One person said it was "Team Rocket's NZ chapter".

A man who answered the gate at the Hells Angels club did not know what Pokemon Go was, and said to "Go talk to the police."
