I had a pond for a year, and nothing arrived, so I got a jar of tadpoles from a friends pond. Last year, one year on, I counted 13 frogs sitting around the pond on a warm day. This year, two years on, and I've got frog spawn for the first time, and some have already hatched into tadpoles. It's interesting watching the pond develop over time. I don't think I'd get newts. They won't be able to jump over the 6 foot high fences!
You'd be surprised what small gaps newts can wriggle under - when we had a smallholding we had a resident colony of Gt Cresteds - every winter some of them would somehow get under our back door and try to hibernate under our doormat - we usually found them after several people had wiped their feet and they were flat as pancakes (I didn't sweep under the door mat every day ).
No wonder the poor things are on the endangered list.
Worth bringing pond dipped water in for the microscopic life.
Dragonfly larvae and the like are often in the sediment at the bottom. Stinks a bit but soon settles.
If they're in the area GCNs may just move in given time. They did here
Be patient and wildlife will turn up, it's still quite early in Spring for pond life, it's will be cooler in the water. Try not to introduce pond life from other ponds because you can spread viruses. : You can try looking in your pond at night with a torch and you might catch a glimpse of a male newt *dancing*.
