A carload of Pokemon Go players were so intent on hunting monsters that they ended up trapped near the Brooklyn wind turbine.

The group had to put in a call to Wellington City Council on Tuesday night, after being stuck behind a gate that shut automatically at 5pm.

"They were fairly sheepish, but they were happy as well because apparently there were heaps of Pokemon up there," council spokesman Richard MacLean said on Wednesday.

Lizzy Eden and Kelsey Thomson kayaked out to the Oriental Bay fountain to capture it within Pokemon Go.

The council was able to remotely open the gates, which are at the bottom of the access road to the turbine, and let the car out.

Though it was all fun and games in the end, the council had a warning for Pokemon chasers.

REUTERS The augmented reality mobile game "Pokemon Go" is at the top of the app charts.

"Our strong advice is, if you don't want to get trapped up on top of Brooklyn Hill, keep an eye on the clock while you're chasing make-believe things.

"You're probably going to get your full bag of Pokemon if you get up there, but don't stay late."

Carly Anderson, community engagement manager for turbine owner Meridian Energy, confirmed the council had to open the gate to let some people out.

"We recommend that those who feel they've gotta catch 'em all do so before 5pm," she said.
