He said it was unlike any plan the council had undertaken when he worked there.
The aspirational plan spans almost 50 years of phased development, from 2017 to 2063.
The vision for the town centre, which could eventually serve a Papamoa East population of 30,000, includes a high street with shopping and a town square fronting the Wairakei stream.
It would sit on land already zoned for a town centre in the Wairakei development, and be surrounded by an employment hub spreading east into neighbouring Te Tumu Kaituna 14 Trust land.
The council could face more than $160 million in potential costs associated with providing services and public facilities in the area, according to rough estimates compiled by Mr Larking.
The estimates included money for water, roading, active reserves, a multi-functional library and community centre, an indoor sports centre, a pool, a bus interchange, park-and-ride facility and the planned Papamoa East Interchange - an on/off ramp connecting the area to the Tauranga Eastern Link.
Mr Larking acknowledged that, while rough, they were "big numbers".
Opting for leasehold arrangements - preferred by Te Tumu landowners - rather than buying land for facilities could "benefit the balance sheet", he said.
The trust represents more than 3700 landowners, who would discuss the plan at a meeting on June 4, trust advisor Jeff Fletcher told the committee.
The trust would seek majority support from the landowners before taking a proposal to the Maori Land Court.
Councillor Leanne Brown called the plan "a great piece of work".
"I am excited but also nervous as this is a massive undertaking," she said.
Councillor Steve Morris said this was a better approach to town centre planning that some past efforts.
"I hope that the reality on the ground does live up to the aspiration."
