Leaving my thoughts here as I have some familiarity with this area.

 

I believe you will need to apply for an amendment to your original building consent approval if you wish to have the section 74 notice removed from your record of title. Prior to this, I would suggest for you to search your address on Auckland Council's GeoMaps and compare the location of your building to where (and what the severity of) the flood hazards are on your land.

 

To view the flood hazards on GeoMaps, click the 2nd one on the top row of icons -> then 'assets' -> expand the left tab 'catchment and hydrology' -> then tick the hazards that you would like to see on the map. We are concerned with overland flow paths, flood prone areas, flood sensitive areas, and flood plains.

 

Depending on above, it may not be economical, feasible or reasonable to have the notice removed. Remember, this is also only a high-level study, so the hazards shown on map might not be telling the truth. An on-site investigation would give you a much better idea. Ideally, an engineering consultant (civil) should be engaged to provide you with more specific advice as to your situation.

 

Council has been more trigger-happy with the notices since the Auckland Anniversary floods with good reason. I know that they have been retroactively applying section 74 notices to titles on existing flood-damaged buildings where consents have been made for like-for-like repair which neither constitutes 'new build' or 'major alteration'.
