It's thought consistency is key as the Government moves to ban all under 18s from buying all Lotto products. 

Currently, only Instant Kiwi products have an age limit.

She told Tim Beveridge she expects little resistance to the change. 

Van Velden says Lotto estimates just 0.2% of all tickets are bought by kids.
