Canterbury weather has a talent for arriving unannounced. A still morning can turn into a nor'wester by lunchtime, and a mild afternoon can be followed by a southerly change that drops the temperature ten degrees in an hour. None of this stops a move, but it does change how you prepare for one.

The nor'wester is the one to plan around

A strong nor'west wind is the most disruptive condition for a move, more so than rain. Anything light and flat becomes a sail: mattresses, bed bases, table tops, mirrors, artwork, sheets of plywood. Two people carrying a mattress across an open driveway in a 60 kilometre per hour gust are not fully in control of it.

On a windy day, load the large flat items early while the crew is fresh, keep doors hooked open rather than propped, and weigh down anything staged outside. Empty boxes blow away with remarkable speed, so break them down or keep them inside. Expect the wind to also dry everyone out and shorten tempers; more water and more short breaks genuinely helps.

Rain

Rain rarely cancels a move, but it does slow it, and slower means more hours on an hourly rate. Prepare for it rather than hoping.

• Have old towels and a mop at both ends, plus a doormat inside each entry

• Lay flattened cardboard, drop sheets or old sheets along the main traffic route to protect carpet and polished floors

• Cover mattresses and upholstered furniture properly with plastic covers, not just blankets, which soak through

• Keep cardboard boxes off wet ground; a wet base collapses without warning

• Load electronics and anything absorbent when there is a break in the weather

Carpet is where the real cost sits. Water plus dirt tracked over a light carpet at either end can mean a professional clean, which is far more expensive than the drop sheets that would have prevented it.

Frost and cold

A Christchurch winter morning can leave driveways, steps and decking genuinely slippery, and the risk is highest early, which is exactly when a move starts. Salt or hose down icy paths before the crew arrives. Check timber decking and metal ramps, which stay treacherous longer than concrete.

Cold also affects belongings. Electronics brought in from a freezing truck should be allowed to reach room temperature before being switched on, because condensation inside a device is a real risk. Plants suffer badly in an unheated truck overnight, so move them in the car.

Heat

Canterbury summers deliver plenty of days over 28 degrees, and a metal truck in the sun is considerably hotter than that. Candles, cosmetics, vinyl records, some electronics and anything sealed with adhesive do not enjoy it. Move heat-sensitive items in an air-conditioned car. Load early in the morning if you can. Keep cold water on hand for everyone, and make sure the crew has somewhere shaded to take a break.

Build a weather buffer into the day

The practical takeaway is to allow more time than the perfect-conditions estimate. Adverse weather is one of the standard reasons a move runs longer, along with access problems and unfinished packing. If your day has no slack in it, weather will find it.

It is also worth understanding where you stand contractually. Most christchurch removal companies state clearly that delays caused by weather, ferry cancellations, road closures and similar events beyond their control are not something they can be held liable for. That is standard across the industry, and it is a good reason not to schedule anything critical for the same evening.

Talk to your crew

If the forecast looks difficult, call your mover the day before. They may suggest an earlier start, an extra crew member to speed up the exposed part of the job, or a slightly different loading order. They do this in Canterbury conditions every week, and their advice is usually better than a plan built on optimism.
