I'd recommend PMing teamplayer2003. He can help you on the pension equivalents over here.
As for a civil service pension scheme, there used to be a state sector superannuation scheme but that is closed to new applicants. Basically each public sector agency now has its own options. I've had experience with three public agencies and they've all had different provisions. My current employer is the best of the three (I wasn't employed by the others but worked with them last year) and they pay $1.50 for every $1 you pay into your super account, up to a max of 9% of your salary (so you pay 6%). Others will simply pay into your Kiwisaver. It just depends on their own policies.
