It's profits are transferred to the NZ Lottery Grants Board to distribute. They try to stop any problem gambling and under-age gambling associated with their products.They are subject to stringent Government monitoring.
A very trustworthy Organisation + website.
Also helpful to the Community because of their Grants.
I occasionally buy a Lotto ticket, online, with no problems securely transferring the monies to the website.
A Good Experience.
