The garden area and dog park hosts 30,000 visits a year and Mr Upperton said the need for a bigger parking area to cater for visitors was "critical".
The current parking area off Inland Rd, in Kerikeri, can only take four vehicles.
An agreement to purchase the land has been drawn up and the trust is under a time constraint of eight weeks for the agreement to go unconditional.
"We will wait and see what the outcome (of the council meeting) is before we get too excited," he said.
Also being discussed at the extraordinary meeting but not open to the public, is a report on the Warawara Forest Economic Development proposal to use ratepayer money to build 2km of road access.
Te Runanga o Te Rarawa, an administrator of Warawara Forest along with Northland Regional Council, Department of Conservation and conservation group Reconnecting Northland had earlier applied to council for a $95,000 grant to develop the road.
At the July council meeting Councillor Di Maxwell described the grant process as "tenuous" when the Paihia and Districts Ratepayers Association questioned public money being given to private landowners.
