I have a 2.8h block at Foxton (closer to Palmerston North than Wellington!!). Deep sand and water table at Â±1.2m. Grass, gums, rabbits, tasmanian blackwood trees.... a smattering of native trees, pines and macrocarpara. What to do, what to do? Found the site while browsing for costs of laying services like water, electricity, telephone... Like the tone so I'll sign in rather than lurk!~
Don't do anything for a while, see what the site is like over a period of time...and research, research, research the options until you find something that appeals...different folks like different animals/set ups and the trick is finding what matches you and your block conditions...
Take a break...while I take care of your home, your block, your pets, your stock!  PM me...
Welcome Dolf, I agree with Reggit, live with the land for a while. See how the grass grows, or not grows. See where it gets boggy or wet, see where it stays dry.
Watch what your n/bours graze and how much work is involved. What facilities /fencing you will need to deal with them and the time spent in keeping them. If you work away from home, how much time will you have to care for your stock ?
If possible have animals graze your land from a n/bour, this will let you see if they are the ones you may want to own.
My suggestion would be to start with weaner cattle. Already tagged and drenched and all they need is feeding to be able to sell for profit.
Just my personal 2 cents worth 
There are no bad questions only those that are not asked.
