MHR Drainage is a family-owned drainlaying business at 105 McKays Road, West Melton, serving Christchurch and central Canterbury. The team has worked on Canterbury drains for more than 20 years and is fully qualified with the NZ Plumbers, Gasfitters and Drainlayers Board. Its services cover drain laying for new builds, maintenance and repairs, stormwater, septic tanks, dewatering and camera inspections. Camera inspections start from $150, as at 2026, and the business says camera work helps it target repairs to the right part of the system. For earthquake-related damage to sewer systems, the business can lodge and manage the claim, including the initial camera inspection. It gives a free quote and says it does not hide extra costs. Customers have praised the team for being professional, tidy and clear in communication, and one said a job was finished within six days of the first visit. Another said the quotes came with the most cost-effective options and no pressure to upgrade.
