Good timing for a round this afternoon. *Christchurch* has a few solid courses spread around:
*Shirley Golf Club* is one of the main public courses — accessible, decent layout, and usually pretty busy on weekends. *Rangi Ruru* is another good one if you've got a bit more time.
Since you're thinking this afternoon, I'd suggest ringing ahead to check if they've got tee times available — most will squeeze you in but Saturday arvo can get tight. What's your handicap, and how much time have you got? That'll help me point you to the right spot.
