MAINTENANCE · NEW ZEALAND · 3 MIN READ
Your insurance is not a maintenance plan.
A blocked gutter is easy to put off. The damage it leaves behind can be much harder to sort out.

Sudden damage and slow deterioration
Insurance commonly covers specified losses or sudden, unforeseen damage. Wear and tear, corrosion and damage that develops over time are often excluded. Some policies include limited hidden-water-damage benefits, with specific conditions. The cause, timing and wording matter; a photo alone cannot decide cover.
Do not assume every leak is covered, or that every gradual-damage claim will be declined. Report damage to your insurer promptly and ask what evidence and urgent steps they need. Cover for the cause and for resulting damage may differ. Do not wait for more rain or a complete photo record before reporting damage or getting urgent help. Take safe steps to prevent further damage; never put yourself at risk.

Make a plan for this house
List the roof, cladding, gutters, windows, decks, drainage and heating equipment. For each, record the material, installation date if known, manufacturer instructions, last check and next action. BRANZ describes a maintenance schedule as a record of building elements and the care they need.
The right interval depends on materials, exposure and product instructions. A coastal house and a sheltered inland house may need different care. Use a qualified trade for roof access, electrical work or anything outside your ability.

Turn a problem into a useful record
Try a simple entry: “Water stain beside the upstairs window, noticed after rain on 4 June. Photo attached. Builder booked to investigate.” Keep the cause as unknown until someone has checked it. Add the report, quote, completed-work invoice and follow-up photo later.
For budgeting, separate regular care, a known repair and eventual replacement. A quote has a date and scope; an allowance is a planning estimate. Keeping that distinction visible makes your future costs easier to discuss.
ILLUSTRATIVE EXAMPLE
The stain that comes back after rain
You notice a water stain. Record where it is, whether it is wet or dry and when you noticed it; take a photo if safe. A stain by a window and an active ceiling leak can have different causes and urgency. Contact your insurer promptly about damage and arrange suitable expert help. Do not wait for the next rain to report it or prevent further damage. Save the professional findings, repair details and invoices; cover for the cause and resulting damage depends on your policy.
Set a reminder for the follow-up check. The property passport report is a useful snapshot. The subscription is for keeping that timeline current as new work and evidence come in.
YOUR NEXT STEP
A few things you can do now.
- Walk around the house from safe ground and note changes.
- Check for blocked drainage, new stains and deteriorating finishes.
- Keep manufacturer care instructions and dated work records.
- Put the next task in your calendar and budget for it.
