Some people who listen to RNZ love the Te Reo. Some people are indifferent. Some people hate hearing Te Reo on RNZ. So I have a solution. Modify the RNZ mobile app to introduce a Te Reo filter option. The filter would allow a RNZ with or without Te Reo. The app would have to have a few seconds delay to allow for the filter to work.
When Te Reo was being filtered out a user could choose to hear silence or a bird call of their choice. The default bird would be the Great Spotted Shag. Future versions of the app could have further options such as being able to have say 5 seconds of Te Reo every day up to hearing all Te Reo.
