Eligible voters may make a postal vote application (PVA) prior to each election, or apply for status as a "general postal voter" and receive a postal ballot automatically. Postal voters receive their ballot(s) and a prepaid envelope containing their name and address, as well as a predetermined security question from the PVA. Voters are required to sign the envelope and provide the correct answer to the security question. They are also required to have a witness sign and date the envelope. As of 2016, postal votes were able to be received and entered into the count up to 13 days after election day. Following the 2016 election, it was observed that the strict scrutiny process afforded to postal votes was a "significant contributor" to delays in declaring the results of close elections.
