The Prime Minister says New Zealand should benefit from an increase in global wealth. 

Some of the world's largest banks and investment firms are arriving in Auckland, for the Government's Infrastructure Investment Summit.

Chris Luxon and Ngati Whatua Orakei will formally welcome delegates this afternoon. 

Luxon says New Zealand needs to tackle a huge infrastructure deficit. 

He explained we can't fix it with just our own money - and it'll take pools of money within the country, such as the ACC and Super fund, and also overseas funding.
