Come for a walk in Bowman's Bush. Lots of native birds like to play and sing in here.
Park off Ruru Avenue, and follow the track to GZ, it's not a long walk, about 5 minutes. There are a few houses that back onto this park, so recommend this one during the day.
Please pop the cache container back where you find it.
No brute force needed, and please be patient once you have the container in hand.
