The New Zealand Retro Weekly Top 40 Countdown is a weekly trip back in time to New Zealand in the 1970s, 1980s & early 1990s. Rob Walker hosts the show which is a countdown of the top 40 songs as they were on the official NZ Singles charts for the corresponding weekend. It also includes a look at some tracks off some great albums that were on the official New Zealand album charts for that same year and weekend.
