🎉 VICTORY: When collective pressure breaks open secrets and forces positive change! 🎉

After months of persistence, we as a community successfully pushed Auckland Council to fix their unfair stormwater development contributions policy for free-standing and detached homes – and the changes are coming in the new policy (and were actually implemented from August 2024 based on the communications I received).

📋 The Background:

• 2012: Council was told not to create this unfair system for these house types (they did it anyway)

• 2022: PwC reminded them again… they kept taking money because too few knew about it and had their estimates reassessed

• August 2024: Collective pressure seems to have made them change (they officially told me this a couple of weeks ago)

• In the past Council processed multiple reassessment applications by those who ‘knew’ the secret — ssshhhh — few talked about it for fear of retribution or missing out on fees

😂 Personal note: They processed everyone else’s applications but somehow “not” mine when I asked politely in July 2024. Finally got agreement on 28 May 2025 – better late than never! LOL

🏠 What this means for you as a developer under the new policy:

Free-standing and duplex houses on lots under 292 m² will now be assessed on ACTUAL impervious surface area (not the inflated 292 m² assumption).

This could save thousands in development contributions!

⚠️ Critical trap to avoid: If your lot is 292 m² or bigger, DON’T build a small house! Here’s why:

💸 The logic of a cut-off at 292 m² makes no sense to me so I think you should just avoid the ‘gouge’ spot (requesting reassessments can be problematic for some developers 😤:

*** Here is an example of using a fixed charge of $7,000 for 1.0 HUE:

• Smaller than 292 m² lot + 80 m² ISA build = $1,726 stormwater charge
• Bigger than 292 m² lot + 80m² ISA build = $6,300 stormwater charge
• Same house, $4,574 MORE just because your lot is bigger!

😡 Remember building coverage controls: On a 292 m² lot, you can only legally build 175 m² (60% coverage) but you pay stormwater charges as if you built 292 m²! You’re paying for 117 m² more than you are consented to build!

🎯 Smart strategy:

• Section under 292 m²? Build any size you want (up to the 60% limit)
• Section 292 m² or bigger? Build to maximum legal coverage (175 m² on 292 m² section)
• Never build small on big sections – you’ll pay for coverage you can’t even legally build!

💡 Key lessons:

✅ Persistence pays off
✅ Collective action works
✅ Transparency forces accountability
✅ Knowledge is power – understand your development contributions so you can optimise sizing

🤝 Thank you to everyone who supported this campaign. When we work together, we can create positive change that benefits the entire development community.

For years I would plan houses, travel widely and observe communities. I also had the privilege of working for New Zealand's largest dairy company in both New Zealand and Malaysia. All the while supported by my husband and young daughter. After a while, our roles swapped and we moved to the Arabian Gulf. Meanwhile my passion for property and communities continued to simmer.

Along came COVID and had no choice but to pivot... in the words of Robert Frost, I looked for and "found the road less travelled by" and decided that maybe I could "make [a] the difference".

I look for to find insights and built a few of the houses that we need. This means a saleable house and a profitable and sustainable business.
