The main reason for going to Wellington was for a sleepover at Wellington Zoo. My cellphone ate most of the photos I took (well, it tricked me into deleting them :( ) but we still have a few.
We arrived at 7pm and went round the Zoo with one of the keepers. She got the kids to make "enrichment" for the sun bears - a toilet roll filled with raisins and porridge, with the ends tucked in. The next morning we threw them over the fence so the bears could eat them.
