Chelsey is a magazine website for women that includes a NZ Deal Aggregator. It has a standardised format and it has separate tabs for vouchers and products. Chelsey has a brother website called Get Frank which shares the same aggregator. You can subscribe to daily emails from this aggregator but sadly they send you the 10 most discounted deals of the day which (given the way these sites exaggerate their savings) are not always the best deals of the day.
Most people are aware of the PriceMe website where you can type in a product code and see the prices at various (not all) retailers - just the ones that are prepared to pay PriceMe for each click-through. Well PriceMe also has a daily deal aggregator although it's not obvious where to find it. Their daily emails are really well presented but aren't very comprehensive since it's only the deal sites prepared to pay that are included and 1day.co.nz isn't one of them. The presentation on the web is fine BUT it doesn't give a live counter of whether the deal is sold out or not.
Deal Shrimp has a fairly plain presentation with the price (the most important part) being very passive. They do have a great range of sites and also have a fantastic personalisation feature - "My Deals" which can focus in on just the deals on the type of products you're interested in and vouchers in just the regions of interest to you. They don't have a daily email service yet but if they did, and if it sent you your "My Deals" then it would be great.
