Ok Marty, it's a big place to visit. Some back-packers accommodation is pretty good with all age groups so don't be put off that - good way to meet other people too.
If you are starting in Picton then I'd suggest heading for Nelson and then the West Coast. Down to Queenstown, ride on the Earnslaw, drive up the Remarkables Ski Field road for a picnic and a walk at 6000ft. Might see some keas

.
Take the ferry from Bluff across to Stewart Island, visitors enjoy going there. Take a tourist fishing boat trip - half day, simple, and enjoyable. These boats are modern and built for tourism.
Southern Scenic Route, nice drive through farmland, coast, and bush. Check out the petrified forest at Curio Bay - even more fun if there is a storm

You might see penguins on the way.
Get arrested by Scummy at Balclutha (just a bit of local colour to tell their kids about), visit the albatross colony at Otago Peninsula, and drive through Middlemarch, Naseby and over the Dansey's Pass. The point of this is that the South Island has some vast empty landscapes which come as a surprise to people from large populations. Quite striking. Carry on through the Mackenzie Country to Christchurch and maybe check out Akaroa just for a nice spot to visit.
There are penguins in the Antartica Centre in Christchurch and for more exotic animals, Orana Park.
Over and above all of this, I'd recommend visiting a sheep farm if you can. Maybe somebody here can help. Mountains and landscapes are beautiful but many visitors seem to remember farm visits most strongly. Take them into a cowshed at milking time.
