Parliament will debate a bill that would stop foreigners buying farms.
The Green Party bill has been drawn from the member's ballot and they're looking forward to its first reading.
"New Zealanders look likely to become tenants in their own country if we don't address this," co-leader Russel Norman said on Thursday.
"New Zealand land must be kept for New Zealand citizens, permanent residents and companies."
The Greens drafted the bill after the Crafar farms were sold to Chinese company Shanghai Pengxin, a deal they strongly opposed.
They believe public opinion is on their side, but the bill isn't likely to survive its first reading vote because the government has already tightened the rules and thinks it has gone far enough.
