Everything ready,
before you lodge.
Enter the address. ARRO forecasts what the consent will cost, how long it will really take with RFI risk priced in, and where it's most likely to run into trouble, then tells you exactly which documents your site needs. The surprises happen on screen, not at the council desk.
First, the forecast.
Before you commit a cent, know what the consent will cost, how long it will really take, and where it is most likely to bite.
Price the consent before you commit
ARRO estimates the full cost from real council fee schedules and MBIE levies: processing fees, the building levy, and development contributions, itemised so you see where the money goes, not just a lump sum.
- Itemised breakdown of the full consent cost, not a single number
- Council processing fees and MBIE building levy
- Development contributions where they apply
P50 and P90, not a guess
The statutory 20-working-day clock is only the start. ARRO models real elapsed time, including the odds an RFI suspends the clock and how long that adds, and returns a P50 and P90 in calendar weeks, through to CCC.
- P50 / P90 in calendar weeks, lodgement to sign-off
- RFI probability and expected suspension built in
- Statutory processing clock plus real elapsed time
Where this consent is likely to bite
Every forecast carries a graded risk profile: consent complexity, cost overrun, timeline, and site risk, each with the factors driving it and the mitigations that pull it down, so you can act before you lodge.
- Consent complexity, cost, timeline, and site risk graded
- Concrete mitigations attached to every risk
- The factors behind each score, made explicit
Then, the paperwork.
Every document your site's overlays demand, mapped from the council GIS, so you lodge complete the first time.
The exact document set your Canterbury site needs
Enter a Greater Christchurch address and ARRO looks up what actually applies to that exact site, from flood and liquefaction to slope, coastal, tsunami, and heritage. It starts from the baseline set every consent needs, then adds the extra reports and assessments each hazard on your site calls for, and tells you which one triggered each. The list you get is the one this project has to lodge, not a generic checklist you have to work through yourself.
- Every required document listed, with the reason it applies to your site
- Checked against the exact address, not a rough guess by suburb
- Flood, liquefaction, slope, coastal, tsunami, and heritage all covered
- Live across Greater Christchurch - Christchurch City, Selwyn, Waimakariri
Questions we get asked
How is the P50/P90 timeline calculated?
ARRO models the real elapsed time to consent, not just the statutory 20-working-day clock - it prices in the probability an RFI suspends the clock and how long that typically adds, and returns a P50 and P90 in calendar weeks, through to CCC.
What's included in the cost estimate?
An itemised breakdown from real council fee schedules and MBIE levies - council processing fees, the building levy, and development contributions where they apply - not a single lump-sum guess.
Which areas does site-aware forecasting cover?
Greater Christchurch - Christchurch City, Selwyn, and Waimakariri. Enter an address and ARRO queries the councils' live GIS for the planning zone and hazard overlays (flood, liquefaction, slope, coastal, tsunami, heritage) that intersect the site, and lists the documents each one triggers.
What does the risk profile actually grade?
Consent complexity, cost overrun, timeline, and site risk - each with the factors driving the score and concrete mitigations attached, so you can act on it before you lodge rather than after.
