OMG Riccarton (Westfields to be hoity toity) is now a TWO STOREY MALL! When did THAT happen???

My first visit in two years and wah-la!
Just head into the central city and definitely check out Ballantynes department store - sooooo awesome (and a bit pricey I have to say, but you can be surprised as well!). Head over to Lyttelton if here on a Saturday and look at the Farmers Market - the port itself is about to go through major overhaul so it's nothing brilliant ATM. Head into the Square in the city and check out the Town Cryer, or go for a punt on the Avon. Awesome cafes and bars everywhere! All the malls on the outer city are fabulous as well - and there are cinemas everywhere. Drive up over the Port Hills and do the round the bay thing and come back through Lyttelton's tunnel. That's all the touristy kind of stuff anyway.
If you are after nice walks etc there are heaps and heaps, we aren't just about flatness down here you know! I am sure the hotel you are staying at can help you decide what to do :)
