Auckland Council is coming under pressure to prove it can provide enough parks to keep up with population growth.
Parks have been a hot topic at most public meetings about the rule book for growth - the Unitary Plan.
Councillor Arthur Anae took up the concerns at last week's council regional development and operations committee meeting, which approved a new policy for buying land.
"I welcome this but I wonder what forward planning you have regarding sports parks and facilities, with growth of a million people expected over 30 years," he said.
"We need to be well ahead with that and have it in place."
