5:20pm - NZ Post has suspended its delivery and acceptance operations in areas that have a state of emergency in place.

This covers all regional towns and outlying centres around Christchurch, but doesn't include the Christchurch metropolitan area.

"The highway network south of Christchurch is expected to remain closed again tonight (Monday), however, staff remain on stand-by to commence operations if clearance is given," NZ Post says.

"All links from the lower South Island to Christchurch (and the rest of the country) are blocked - we're unable to clear perishable product beyond the Otago area, and customers should be advised to hold these until the links reopen."

NZ Post says they will continue operating transport services between Dunedin and Invercargill, and Dunedin to Central Otago, but all other transport services operating south of Christchurch will be suspended.

"Our planning over the next few days will focus on the staging and management of the freight backlog that will continue to build in Christchurch," they say.

"At this stage, it is expected the backlog will take the rest of the week to clear. As always with events like this, NZ Post's primary focus is on ensuring the safety and wellbeing of our people."

5:05pm - Waka Kotahi NZTA has given an update on state highways closures in the area.

SH1 Temuka is open from Arowhenua Rd to Donald St, but remains closed from Donald St to Lynnford Rd in Hinds.

SH1 Burnham to Dunsandel, SH73 Springfield to Castle Hill, SH75 Little River, SH77 Darfield to Winchmore, and SH79 Fairlie to Rangitata remain closed.

4:50pm - DairyNZ is urging Canterbury farmers to look out for each other and seek support if needed.

"Good advance warning did enable many farmers to be prepared but we are working closely to monitor the situation and encourage farmers to keep farm teams and neighbours safe," head of the South Island Tony Finch says.

The flooding also comes amid Moving Day with many farmers attempting to shift properties and livestock.

"Farmers who haven't started shifting should only move stock if the roads are confirmed as open throughout the route and the destination farm can receive stock," Finch says.

"We encourage the farm owners, sharemilkers and graziers to discuss Moving Day plans and be flexible – as we know flooding has resulted in road closures and flooding on properties. Keep in close contact with transport providers."

People who need urgent support are asked to contact your local Civil Defence, or in an emergency situation dial 111.

Both DairyNZ (phone 0800 4 324 7969) and the Rural Support Trust can be contacted for recovery support and advice on 0800 787 254.

4:30pm - People affected by the flooding are urged to contact their insurers and record the damage before cleaning up.

"We've dealt with a number of insurance-related complaints over the years where people have rolled up their sleeves and got in straight away - cleaning up and throwing away items," Insurance and Financial Services Ombudsman (IFSO) Karen Stevens says.

"Later in the insurance claims process, this can lead to problems when proving damage. Being clear about things from the start can prevent angst later down the track."

She says for those who are unable to get back their homes, contact your insurer to ask about temporary accommodation cover, under either your house or contents policies.

4:10pm - The New Zealand Red Cross says its volunteers are "supporting people affected by the Canterbury flooding".

"They are visiting residents to check on their needs and advising them to be prepared to evacuate, should the situation worsen."

4pm - SH8 from Fairlie to Tekapo has been opened, according to the Mackenzie District Council.

"Surface flooding remains and caution is advised."

3:35pm - The Student Volunteer Army (SVA) says it's "poised and ready to assist" with the cleanup when the flooding subsides in Canterbury.

"After the earthquakes, farmers in the regions helped out Christchurch in a major way. After these floods, we're going to be focused on returning the favour. We encourage anyone who has the time and capacity to support the clean up efforts to join us - everyone is welcome to lend a helping hand," founder and chief executive Sam Johnson says.

Anyone wanting to assist is encouraged to download the SVA app and keep an eye on the group's social media.

If you need help, let SVA know by calling 0800 005 902 or emailing hello@sva.org.nz.

SVA operations manager Penny Roy says "for the moment, the focus is for everyone to act with extreme caution and to avoid any non-essential travel". 

"As it is appropriate, we'll update our volunteers about safely getting out to assist with the clean-up."

3:10pm - The Ashburton District Council has issued the below update:

Methven & Mt Somers water update: The water tankers in Methven and Mt Somers are being refilled this afternoon, and are scheduled to be refilled again from 7am tomorrow morning (1 June). In Methven, the water tanker is located near the public toilets on Main Street, while the Mt Somers tanker is located near the Fire Station/General Store.

Bring along containers to fill for your drinking water. If you are unable to get to the tankers to access the water, please call Ashburton Civil Defence on 03 307 7700.

Welfare information: There are currently NO evacuation orders in place for the Ashburton District. If you need to self-evacuate, consider if there are friends or family  that you can stay with. If you don't  have somewhere safe to go, please contact Ashburton Civil Defence on 03 307 7700.

Water contamination: Residents are reminded to continue avoiding floodwater, as wastewater from the Ashburton pond treatment facility on Wilkins Road, Tinwald has flooded. Potentially contaminated water is now mixing with floodwater downstream from Wilkins Road. This is a public health risk. Additionally, wastewater is flowing into Carters Creek which feeds Lake Hood. Residents should avoid the water and assume that it is contaminated. If you do come into contact with flood waters, change out of any wet clothes and shoes and put them aside to be washed later. Wash skin that has come into contact with flood waters, and wash your hands as soon as you reasonably can – or use an alcohol-based hand sanitiser.

3:05pm - Waka Kotahi NZ Transport Agency have advised Mackenzie District Council that they are expecting SH8 between Fairlie and Tekapo to open early Monday evening.

Motorists are warned there will still be surface flooding and possibly debris so they will be urged to take extreme cation.

SH79 from Fairlie - Geraldine remains closed. 

"There is significant work to do but NZTA are hopeful of getting it open tomorrow (Tuesday)."

2:45pm - River levels in Ashburton have been falling but it could take two or three more days to drain and people need to keep their bags packed in case stopbanks burst, Ashburton District Mayor Neil Brown says.

Brown spoke alongside council chief executive Hamish Riach in the press conference.

He said while it had stopped raining the river was still full and there was still pressure on some spots.

Residents were still required to have a bag packed and be prepared to evacuate, he said. It could be another two or three days before the catchment dropped back to normal levels.

Riach said it may feel like it's "just a rainy day" but the pressure on the rural area was high with a lot of surface flooding. There were other issues including floodwaters getting into the wastewater system.

Four bridges were gone, and there were numerous roads where the seal had been lifted off the road, Brown said.

Seventeen roads were closed, including the Gorge Bridge and Rakaia Bridge - the roads to Christchurch.

Residents should avoid any unnecessary travel and remain at home, Brown said.

"There is a lot of damage, a lot of water has been swirling around, creating holes in the road, and if there's water still in them, you won't see them and your car will just drop into them."

"The Selwyn River/ Waikirikiri deep flooding on SH1 at Dunsandel means this highway link south of Christchurch is unlikely to open today.

"Many local roads are also under water, so your local council's Facebook pages and emergency management pages are the best places to check."

10:15am - Here's a summary of the conditions from throughout the region from Environment Canterbury: 

  • Ashburton: There is extensive surface flooding across the district and numerous road closures. No current concern at Jessops Bend on the Ashburton River which is the main breakout point that could affect the township
  • Selwyn: The Selwyn River is running in high flood. Flows have peaked at the top of the catchment and are still rising at the bottom (Coes Ford). SH1 is closed north of Dunsandel because of overflows
  • Waimakariri: Low lying areas of The Pines Beach, particularly around Dunns Ave have been advised to evacuate. Residents in the Eyre River evacuation area are now able to return to their homes.The Ashley River is starting to drop at the gorge, and is still running high through the lower reaches. Eyre and Cust river levels have started to drop.
  • Hurunui: High flows in most Hurunui District rivers, and may be some flooding along river margins
  • Kaikoura: No known issues of concern.
  • South Canterbury: Most of the rivers are now falling from peak flows but will remain high through Monday. Those living near affected rivers need to be wary of changes in river flow patterns and the potential for erosion within the riverbed as flows drop away and gravel is redistributed. New problems can arise as flows recede back to normal and adjacent landowners should monitor their own situations. Numerous road closures have occurred and are expected to remain into Monday.

10:10am - Selwyn Mayor Sam Broughton says 300 people have already been evacuated across the district so far and more are on the move.

9:40am - Christchurch's North South Holiday Park is offering free rooms to anyone affected by the evacuations.

9:30am - A wastewater facility has flooded in Ashburton, prompting a warning to avoid all contact with floodwaters.

"Please boil all water for drinking, cooking and personal uses such as toothbrushing for at least one minute."

8:15am - The Government has contributed $100,000 towards a Mayoral Relief Fund to support Canterbury communities. Acting Emergency Management Minister Kris Faafoi earlier told The AM Show people need to be patient as officials work to get things back to normal.
