The Dunedin City Council confirmed in August it had granted owners Geoff and Tracey Scurr, of Geoff Scurr Contracting, consent to expand the quarry.
The decision came with a list of 24 conditions designed to protect neighbours from the worst effects of noise, dust and the appearance of the Pryde Rd quarry.
That included a 30,000cu m limit on the amount of rock to be extracted each year - less than the maximum 45,000cu m the Scurrs wanted in some years.
However, Mrs Scurr said this week her company was appealing three of the conditions imposed by the council.
Three neighbours had become parties to the appeal, two of them supporting the changes sought and one opposed, Mrs Scurr said.
A mediation hearing was scheduled to be held late next month, she said.
The company wanted to reduce rock crushing, loading and transporting activities on Saturdays, and in return start weekday rock crushing activities - when needed - one hour earlier than allowed, at 7am, not 8am.
The company also wanted to be allowed to carry over some unused rock extraction capacity from one year to the next, while remaining within the average 30,000cu m annual limit "or thereabouts" required by the council, she said.
A clarification to a condition defining "crushing time" was also being sought.
Neighbours concerned about the quarry's plans had worried expansion and an increase in heavy vehicles on Pryde Rd would erode safety and create more problems with dust and noise.
However, those spoken to had declared themselves happy with the council's decision to grant consent, because of the conditions imposed.
Mrs Scurr said the company had conducted "extensive consultation" with neighbours before and since the decision, and felt the changes sought were "balanced and will better meet the needs of all parties".
"We believe this can be achieved without marginalising the operation, which supplies necessary products to the local market and needs to be able to continue doing so in a cost-effective manner."
