The Government could be willing to let more foreign investors into a summit it announced today, as demand exceeds spaces.

The Prime Minister's announced the two-day event in March - designed to encourage foreign investment in New Zealand projects and industries. 

Infrastructure Minister Chris Bishop says the Government funded, 100-person, invite-only event is already over-subscribed.

He says the focus is inviting the highest value investments and global leaders in infrastructure. 

"We're not going to have a thousand people, but what we are trying to do is get high-value investment into New Zealand. We want jobs and growth, and there's a huge degree of interest from around the world in it."
