The cost of keeping Government-owned assets could be more than the return it's getting from them.  

A report by The New Zealand Initiative says the Government owns $571 billion in assets, yet the returns from them don't even cover the interest on loans used to buy them. 

Author Bryce Wilkinson is calling for a review to identify if assets should be sold, and if so, which ones.   

He says the Government should be asking if someone else could put the assets to better use to improve public access.
