How long does a kitchen renovation take?

4–10 weeks from demolition to handover for a mid-range to full renovation. Add 4–8 weeks lead time for custom cabinetry ordering before work begins.

Can I keep my kitchen partially functional during renovation?

Rarely. Once demolition starts, the kitchen is unusable until fit-off (typically 3–4 weeks for mid-range, 5–6 for full gut). Plan a temporary kitchen elsewhere in the house.

Do I need building consent for a kitchen renovation?

Only if you are making structural changes (removing walls), significantly relocating plumbing, or altering the electrical layout. A like-for-like replacement in the same footprint does not require consent.

Stock cabinets or custom: which should I choose?

Stock/flat-pack works well for standard layouts and budget renovations. Custom joinery is worth it for non-standard spaces, integrated appliances, or when you want specific materials and finishes. The sweet spot for most Christchurch homeowners is a mid-range custom kitchen from a local joiner ($20,000–$35,000 for cabinetry alone).

What is the most common mistake in kitchen renovations?

Underestimating the cost of layout changes. Moving the sink or cooktop sounds simple, but it requires plumbing and electrical relocation, potentially new floor and wall runs, and sometimes consent. Budget $5,000–$10,000 more than you think for any layout change.

Should I splurge on appliances or cabinetry?

Cabinetry. It determines the look, feel, and longevity of the kitchen. Appliances can be upgraded later; cabinetry cannot without another renovation. Spend 40–50% of your budget on cabinetry and benchtops.

The Decisions That Move the Price

Kitchen renovation costs are driven by a handful of binary decisions. Each one can swing your budget by $10,000 to $30,000. Understanding these upfront prevents budget blowouts.

Cabinetry is the single biggest cost decision. Stock or flat-pack cabinetry runs $8,000 to $15,000, while custom joinery costs $20,000 to $50,000+. That is a potential $28,000 to $35,000 swing on one line item. Decide this first and your entire budget range becomes clear.

Benchtops range from $2,000 to $4,000 for laminate up to $5,000 to $15,000 for engineered stone or granite. The price difference of $3,000 to $11,000 is significant but manageable. Choose based on durability needs and how the kitchen will be used.

Appliances as a package cost $5,000 to $10,000 for mid-range brands, or $15,000 to $35,000 for premium and integrated options. This is a $10,000 to $25,000 swing. Unlike cabinetry, appliances can be upgraded later without another renovation.

Layout changes are where costs jump unexpectedly. Keeping the same footprint adds nothing structural. Removing a wall and creating a new layout adds $15,000 to $30,000 for engineering, consent, and associated building work. This is the decision that turns a $50,000 renovation into an $80,000 one.

Plumbing relocation is often underestimated. Keeping sink and dishwasher in the same location costs $1,500 to $3,000 for connections. Moving them to a new position costs $4,000 to $8,000 due to new floor and wall runs. Budget $2,500 to $5,000 more than expected for any plumbing relocation.

Splashback options range from $500 to $1,500 for painted or acrylic, up to $2,000 to $5,000 for tiled or glass. A smaller swing ($1,500 to $3,500), but one that significantly affects the visual result.

Key takeaway: the single biggest cost decision in a kitchen renovation is cabinetry. Stock cabinetry at $12,000 vs custom joinery at $40,000 is a $28,000 swing on one line item. Decide this first and your budget range becomes clear.

Kitchen Renovations in Christchurch: What's Different

Open-plan dominance. Most modern Canterbury homes and renovations trend toward open-plan kitchen/living. If you are converting a galley kitchen, budget for structural work (load-bearing wall removal) which adds $15,000 to $30,000.

1970s to 80s housing stock. Christchurch has a large volume of homes from this era with closed-off kitchens, outdated wiring, and galvanised plumbing. Expect hidden costs once walls are opened.

Consent requirements. If you are removing walls, relocating plumbing significantly, or altering the electrical layout, building consent is required through CCC (or Selwyn/Waimakariri for surrounding areas). Budget $1,500 to $3,000 in consent fees and 3 to 5 weeks in processing time.

Earthquake legacy. Some homes have minor structural damage that only becomes apparent when walls are opened during demolition. A contingency of 10% is essential for any Christchurch kitchen renovation.

What to Expect During a Kitchen Renovation

Understanding the process helps you plan around the disruption and know what each stage involves.

Design and selection

2–4 weeks

Your kitchen layout is finalised, materials are chosen, and the quote is confirmed. Your kitchen remains fully functional during this stage. Take your time here because changes after this point cost money.

Ordering

2–6 weeks

Cabinetry and materials are ordered. Custom joinery has longer lead times than stock options. Your kitchen remains fully functional. Use this time to set up your temporary kitchen station.

Demolition

1–2 days

The old kitchen is removed and services are exposed. From this point forward, your kitchen is unavailable. This is fast but disruptive.

Structural and services

3–7 days

Wall removal (if required), plumbing rough-in, and electrical rough-in are completed. This is when surprises behind walls are discovered: old wiring, damaged framing, or asbestos.

Lining and prep

3–5 days

New wall linings are installed, floors are prepared, and painting happens before cabinetry arrives. Everything must be plumb, level, and ready to receive cabinets.

Cabinetry installation

3–5 days

Cabinets, benchtops, and splashback are fitted. This is when the kitchen starts looking like a kitchen again. Precision matters here because everything is visible.

Services fit-off

1–2 days

Sink, appliances, rangehood, and lighting are connected. Your kitchen is nearly functional.

Final touches and handover

1 day

Touch-up painting, handles, cleaning, and final inspection. Your kitchen is done.

Living without a kitchen: plan for 3 to 6 weeks without a functioning kitchen. Set up a temporary station (microwave, kettle, toaster, fridge) in another room. Budget for more takeaways than usual.
