SmartGrowth's implementation manager Justine Brennan described the settlement pattern review as a complex project of critical importance, with long-term decisions needed for land-use, infrastructure and funding.
She said the evidence behind the review needed to be robust, but the small pool of technical staff from partner councils responsible for gathering this evidence had many other competing demands on their time.
Regional councillor Paula Thompson supported employing the extra staff so there was no tension between SmartGrowth and the Tauranga City and Western Bay District councils. "Let's not put ourselves in the position of having ongoing tension."
Tauranga Mayor Stuart Crosby said there was no guarantee that his council's $80,000 share would survive the 2014-15 budget process.
Ms Brennan said the risks of being inadequately funded included their work programme being dominated by the settlement pattern review, with not enough progress on other aspects of the new SmartGrowth strategy.
Fifty of the 126 actions listed in the 2013 review of SmartGrowth were deemed to be urgent or priorities.
