Queen Elizabeth II is being honoured with a national period of mourning and a memorial service.
Buckingham Palace announced the monarch's death at age 96 on Thursday morning (local time).
"The Queen died peacefully at Balmoral this afternoon," the Royal family said. "The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
Prime Minister Jacinda Ardern told reporters New Zealand will hold a minute of silence when it is "most appropriate" and an Official State Service.
"The Official State Service for New Zealand will not happen until the official service for the Queen in the United Kingdom and that's what protocol would dictate," Ardern said.
"We would expect that once we have arrangements or are aware of arrangements in the UK then we set down the plan for New Zealand. In the meantime, we will have condolence books available here in the Capitol. I imagine many may wish to leave tributes.
"The NZ Defence Force will be issuing details soon of a likely gun salute. We will be scheduling a moment of silence as well [but we are] just working through the most appropriate time for New Zealanders to join in that moment."
Here's everything you need to know about how the Queen's death will impact New Zealand.
Queen's Birthday
The Governor General's Office told Newshub as far as they're aware there will be no changes to the Queen's Birthday holiday.
"The public holiday in June will remain. I am not aware of any plans to add a further holiday in November," a spokesperson told Newshub.
However, the Department of Prime Minister and Cabinet told Newshub the Queen's Birthday will now be known as the King's Birthday Weekend.
Money
The Reserve Bank of New Zealand has revealed Aotearoa's banknotes will change - but ones with the Queen's face on them will still be accepted.
"There is no immediate impact on New Zealand’s banknote and coins designs and cash use as a result of a change in Sovereign," a spokesperson said.
"All existing coins and $20 banknotes in circulation featuring Queen Elizabeth the Second remain legal tender. It will be several years before we need to introduce coins featuring King Charles the Third, and longer until stocks of $20 notes are exhausted."
The spokesperson said there will be no change in value to New Zealand banknotes or coins with an image of the Queen on them.
"Banks, retailers, individuals and others using or handling cash will not need to do anything differently when we introduce new coins bearing the image of the King. We will let everyone know when new coins are due to enter circulation."
"The Queen is likely to remain on $20 banknotes issued from existing stock for many years to come. We manufacture these notes infrequently and do not plan to destroy stock or shorten the life of existing banknotes just because they show the Queen. This would be wasteful and poor environmental practice.
"We will prepare to change out the image on coins for one approved by King Charles working in
conjunction with our mints who produce for multiple Commonwealth countries."
Passports
The Department of Internal Affairs has also assured New Zealanders their passports are still valid after the Queen's death.
"New Zealand passports continue to be valid despite the passing of Queen Elizabeth II who appears on our passports as Head of State," the Department said.
"New Zealand passports are still current, valid and can be used for travel and as proof of identification. They will continue to be valid until they expire."
In a statement, the Department said in the future passports will be issued in the name of the new sovereign.
Stamps
New Zealand Post told Newshub there will be no change to general stamp issues as a result of the Queen's death.
Flags flown at half-mast
The Ministry for Culture and Heritage revealed on Friday all flags will be flown at half-mast across New Zealand as a sign of respect for the Queen.
"As a mark of New Zealand’s deepest mourning and respect, the New Zealand Flag is to be flown at half-mast on all Government and public buildings with immediate effect to mark the death of Her Majesty Elizabeth II, Queen of New Zealand," The Ministry said in a statement on Friday (NZ time). The flag should continue to be flown at half-mast up to and including the day of the Queen's State Memorial in New Zealand, except on Proclamation Day (being the day when the new Sovereign is announced officially) when the New Zealand Flag is to be flown from the top of the mast, the Ministry instructed.
"The flag is half-masted by first raising it to the top of the mast and then immediately lowering it slowly to the half-mast position. The half-mast position will depend on the size of the flag and the length of the flagpole. The flag must be lowered to a position recognisably "half-mast" to avoid the appearance of a flag which has accidentally fallen away from the top of the flagpole," the Ministry said.
Newshub senior political reporter Amelia Wade told AM flags are flying at half-mast at Parliament already as a sign of respect for the Queen. Flags were also flying at half-mast on Auckland's Harbour Bridge.
Crowned in 1953, the Queen was the longest-reigning British monarch and the longest-serving female head of state in history.
